During its 11-season run, more than 900 pitches have been presented on ABC business reality series Shark Tank with more than 60% of these succeeding in landing a deal. But while most of the pitches tend to go well, a couple of them have exploded into heated arguments between the entrepreneurs and the sharks or between fellow sharks.

In other reality shows, such arguments tend to lead to physical altercations but being a business show, more decorum is seen on Shark Tank with only words being exchanged. Nevertheless, most of the arguments have been impossible to forget. Here are the best ones on the show so far.

An Entrepreneur Tells The Sharks They Are Worthless

Scott Jordan insults the sharks

In Season 3, an entrepreneur named Scott Jordan showed up at the tank, seeking a $500,000 investment for 15% equity in his attire company, SCOTTeVEST. His product was all about a vest that allowed people to store all their gadgets in it.

When he mentioned his $5 million worth of sales, Kevin made an offer but Jordan opted to step out and call one of his rich friends for advice first. After the call, Jordan was more aggressive than necessary, thus angering the sharks. A heated argument ensued before Jordan used the sharks' own line by shouting "You're out!" to all of them. He then called them worthless and left. Pretty bold!

In November 2016, real estate agent Junior Designer pitched his product to the sharks. It was a smart lockbox named Toor that could be operated using a smartphone.

Guest shark Chris Sacca argued that the idea wasn't innovative because it had been done before. Mark disagreed, leading to a heated argument between the two billionaires as well as the entrepreneur. Eventually, a frustrated Sacca stood up and questioned Mark's intelligence. He suggested that it was surprising Mark made all that money despite being dumb. Wow!

And as Lori was speaking, Malepati interrupted her again to talk to another male shark. This caused Lori to go into a rant about how she wasn't being respected as the only female shark on the night. Malepati apologized but Lori wanted to hear none of it. Later on, the other sharks consoled her, arguing that maybe Malepati was just nervous.

Entrepreneur Ryan Naylor once stepped into the tank to pitch a new watch that was able to monitor iron levels in the body. He called his business Esso Watches. However, as soon as he came in the sharks began tearing into him, with Cuban calling his product a scam.

However, Naylor totally refused to defend his product thus making the sharks even angrier. Each of them called him out for not being passionate but he didn't care. Eventually, Robert gave him credit for taking all the heat and still seeming unbothered.

The two doctors were pitching a social media app for doctors called RoloDoc. They refused to answer serious questions regarding their business, leading to all the sharks pulling out. Cuban went one step further by lambasting them and congratulating them for having the worst pitch of all time

Lori wanted in on the deal but Kevin was keen on doing it alone. Dobson reluctantly accepted the deal before he jokingly told Kevin not to lose Lori's number. Kevin didn't seem too impressed but Dobson made matters worse when he asked Lori if she had anything to add. Kevin got angry and shouted: "That's it. I'm out. Get out of there. See ya, buddy. Goodbye, take the broom." Soon after that, Barbara lashed out at Kevin, referring to him as too mean. But as expected, Kevin wanted to hear none of it.

When athlete Jared Ward and his two business partners pitched a unique massage therapy ball called MyoStorm to the sharks, they were all interested. Mark made the first offer and demanded an immediate decision but the two entrepreneurs insisted on listening to other offers first.

Mark then got angry and went out. All the other sharks made offers and upon realizing they had the advantage, the entrepreneurs wanted each shark to prove their worth. Eventually, Lori got the deal, leaving everyone else angry. While they were leaving, Daymond told them "Roll your a**es out of here," while guest shark Matt pretended to throw their product.

Kevin Tells A Contestant To "Get The F*** Out Of Here."

Heated argument over Pavlok in Shark Tank

In the Season 7 finale, a contestant refused an offer from Kevin even when all the other sharks had dropped out. Consumer-electronics company Pavlok's founder Maneesh Sethi stated that he had no intention of having Kevin as an investor because he didn't like his personality.

Kevin didn't take Sethi's remarks kindly and went on to use a couple of expletives. Kevin had offered $500,000 as a loan with an interest of 7.5% interest for a period of 24 months. And when Sethi tried to confirm if every other shark was indeed out, Kevin added a "F*** You," before asking him to leave.

Richard Branson argues with a contestant in Shark Tank

In one of billionaire Richard Branson's many guest appearances on Shark Tank, he took offense to Cuban calling an entrepreneur a gold digger. Cuban explained that he used the term because the entrepreneur was seeking money that she didn't need.

Branson took offense to the term so he poured water at Cuban. Not one to turn the other cheek, Cuban poured water at him too. Interestingly, they were all fighting over a product that is supposed to help people calm down. The product was Simple Habit by Yunha Kim.
