Two and a Half Men is a sitcom that aired on CBS from 2003 to 2015 starring Charlie Sheen, Jon Cryer, and Angus T. Jones. The show consisted of twelve seasons and more than two hundred episodes in total. It became incredibly popular and garnered several Primetime Emmy Award nominations during its run. The series was so famous it even shared an unlikely crossover with the crime series, CSI.

However, it wasn't without its drama. Two of the show's main characters, Sheen and Jones, both exited the sitcom in a tremendous cloud of controversy. Despite all this, it is still considered one of the most successful sitcoms of all time. We're taking a look at the ten lowest-rated episodes out of its twelve-season run, according to IMDB.

Season 12, Episode 2 - A Chic Bar in Ibiza

For the fans who hoped Walden's proposal wouldn't pan out, it was hard to watch this episode follow through on it. It would be one thing if this show wanted to have two gay leads, but the entire plotline plays out as a joke, which is pretty offensive.

By episode's end, Walden and Alan marry at the courthouse. But it doesn't go off without a hitch. Walden upsets Alan by asking him to sign a pre-nuptial agreement. Walden clarifies their wedding is a business arrangement. They wind up making up and move forward with their marriage.

Season 12, Episode 1 - The Ol' Mexican Spinach

However, Walden somewhat overreacts and decides, suddenly, that he wants to have a child. It's hard for a single male to adopt and Walden has no one to propose to, on impulse, he proposes to Alan. Fans weren't happy about this new development or Walden's sudden desire to have a child.

Season 9, Episode 3 - Big Girls Don't Throw Food

Following up on the rocky premiere of the ninth season, Ashton Kutcher begins to settle into his new role on the series as Walden and taking over the spot left behind by Charlie Sheen's departure. This episode features some of the first Walden and Jake interactions, but it doesn't go very well.

Walden tries to give Jake some advice about the fact he dropped out of school, which makes Jake try to convince Alan that he should be able to drop out as well. The bulk of this episode is about Alan moving into Walden's beach house. Except, awkwardly, Alan and Jake wind up having to room together.

Season 9, Episode 2 - People Who Love Peepholes

This episode served as the second part of the two-part season nine premiere. It came on the heels of the Charlie Sheen controversy. Given people were still bitter about Sheen's departure and the publically known behind-the-scenes drama that occurred during the summer before the air date.

It's no surprise it ranked so low. People were beginning to acclimate to Kutcher being the Sheen replacement, and the episode is still awkward and clunky, though not quite as bad as the first part of the premiere. It would take some time before the hole left by Charlie began to feel less noticeable.

Season 12, Episode 15 - Of Course He's Dead

You might be surprised to see that the series finale of Two and a Half Men takes the place of the number one lowest-rated episode in the show's history. Then again, depending on how you felt about the finale, maybe it makes perfect sense to you. After all the controversy during the run of Two and a Half Men, Charlie Sheen doesn't reprise his role in the final hour.

But that didn't stop Chuck Lorre from bringing on a body double and killing off the once title character by having a grand piano fall on him. It's a weird way to end the show. Depending on who you ask, it was either a stroke of genius or total idiocy.
