In the history of television, few shows have been as much of a joke machine as Cheers was. Set in the Boston bar, the comedy could often seem like every other line of dialogue was a set up for a satisfying punchline.

Just because Cheers had plenty of hilarious jokes, though, that does not mean fans caught them all on the first go around. Some of the jokes on Cheers are real thinkers and require a rewatch to not be missed.

The Psychology Of Frasier

As some of the jokes were real thinkers, it's no surprise that many of the hidden ones came from Frasier Crane, the show's real thinker. As a psychologist, Frasier always had thoughtful opinions on matters and it came out in his jokes, too.

Frasier, who later received a spin-off, once ruminated on confronting death before deciding that this was not the most thoughtful way to live life. Instead, he said, "A real man is someone who makes gobs and gobs of money, like me." Of course, one must ruminate on mortality to get the full impact of this joke.

Frasier V. Lilith

Frasier was not the only intellectual on Cheers, though. Lilith Sternin was also an accomplished academic who could speak in tongue ties as well as Dr. Crane.

The two frequently got into arguments, including one moment when Frasier said he appreciated Lilith's candor before doubling back and saying, instead, "I feel like striking you." If he had just used "honesty," the joke would be an obvious one, but the word choice of "candor" makes this line more thoughtful.

Gardening And Madness

In contrast to Frasier, Cliff is a character who was often the butt of many jokes. At one point, he ponders about his own weirdness before Carla says he is beyond weird. Norm adds, "Now you're boldly going where no man has gone before."

This is a Star Trek reference, for all the fans of Cheers who never crossed over into the sci-fi television series. It was a fun cultural reference for the show to make when many of the lines had to do with sports.

Position Of Authority

Jokes between the Sam and Diane and Sam and Rebecca pairings were always welcomed on Cheers. At one point, Rebecca took a dig at Sam by saying that he struggled to date women who were in positions of authority.

Sam countered this with, "I've never had trouble with a woman in any position." It's a clever bit of wordplay that goes by quickly on the initial watch. But Cheers always excelled with their double entendres.

Stages Of Grief

Returning to Frasier's proclivity for psychoanalysis, he would occasionally lay his smarts on Sam and Diane, as well. Sometimes, he was pushed to the breaking point, like when he snapped out into a crazed monologue about how the two need to admit their passion for one another.

Of course, in classic Frasier fashion, his dialogue alludes to psychology. He says, "You can just get on with your denial fest." The comparison of denial, a stage of grief, to Sam and Diane's relationship is certainly an apt one, considering the grief it wreaks on the entire bar.

Norm's Liver

As quick as many characters on Cheers were to take a dig at Cliff, Norm was arguably quicker when it came to taking a dig at his own liver, the body part that suffers the most from alcohol consumption. There were many, many liver jokes on Cheers.

It even becomes Carla's suggestion for Rebecca when the latter says she needs something old, borrowed, and blue. The joke already has the layer of being connected to a wedding, but Norm adds another layer when he says, "I'm almost finished with it." Beer in hand, of course.

I Thinks

Woody smiling behind the baar in Cheers

It is not easy to miss a joke from Woody, considering he is the simpleton of Cheers. However, one grammatical joke made for some fun humor could've been easily missed.

When Diane quotes Shakespeare, including the word "methinks," Woody says, "Shouldn't it be 'I thinks'?" Carla retorts immediately, "Not in your case, Woody." One would have to be able to recall classic grade school lessons to appreciate the academia behind that joke on a quick first turn.

Wade Boggs

When Wade Boggs, one of the great players in the history of the Boston Red Sox, entered the bar, no one believed his identity. Norm joked that he was Babe Ruth, an obvious choice for a famous baseball player about whom to be sarcastic.

But Cliff threw out a much less famous name: Dizzy Dean. Dean was a great ballplayer, but definitely not at the Ruth or Boggs level. The joke was topped off by Woody adding, "I'm Woody Boyd." Never change, Woody.

Freudian Slip

Calling Dr. Frasier Crane for this joke as Dr. Sigmund Freud is definitely in his wheelhouse. When Woody asks about what a Freudian slip is, though, Cliff chimes in with his own know-it-all explanation that gets away from him.

He says, "That's when you say one thing when you're actually thinking about a mother." Cliff's weirdly intimate relationship with his mother was well-known on Cheers, but the accuracy with which he summarized Freud's theories in just one joke line was definitely easy to miss.

Garden Of Cheers

Characters like Diane and Frasier could make many allusions to intellectual topics over the course of Cheers, as evidenced by some aforementioned hidden jokes. However, one of the best came when Diane alluded to religion.

Diane's joke, "If ignorance is bliss, then this is Eden" is a joke that one can miss if they are not paying attention. But it shows that Cheers, with all of its inane patrons, could resemble God's original paradise, albeit in a warped way.
