Hundreds of entrepreneurs have pitched their companies on "Shark Tank" since the show debuted in 2009, but some of the most memorable pitches are the worst ones.
They stand out for different reasons. In some, the products are ridiculous. In others, the entrepreneurs are completely unprepared or so arrogant they appear clueless.
In anticipation of the Season 8 premiere on Friday, we've gathered the Sharks' least favorite presentations as well as our own picks for the worst pitches in the show's history.

Pavlok, Season 7
Maneesh Sethi's pitch went so off the rails that it ended with Kevin O'Leary calling Sethi an "a--hole" and telling him to "get the f---- out of here."
Sethi came into the Tank asking for $500,000 in exchange for 3.14% equity of his company Pavlok. It manufactures wristbands which, through either a manual or automatic prompt, shocks its wearer when performing a bad habit.
It's inspired by decades-old Pavlovian research, but when Mark Cuban asked Sethi if there were any peer-reviewed studies on the effectiveness of his invention, Sethi could only point to an 8-person pilot program with the University of Massachusetts at Boston (not televised) and the research that predated Pavlok. Cuban and Sethi started arguing with each other and Sethi lost his cool, once grabbing his face in frustration.
O'Leary eventually told Sethi he was intrigued and made an offer that Sethi liked. But Sethi refused it, saying, "I would take an offer from anybody besides Mr. Wonderful," using O'Leary's nickname. He clarified that it was indeed personal, and that's when the altercation happened.
"Oh, well ... are you all out?" Sethi asked.
"F--- you," O'Leary responded.
The Skinny Mirror, Season 8
Belinda James is the founder of The Skinny Mirror, a company that sells custom mirrors to individuals and businesses that makes the viewer appear skinnier than she is (James' target audience is women). She only sold $85,000 worth of her mirrors when she walked into the Tank, but valued her company at $1 million, asking for $200,000 for 20% of her business.
In her pitch, James admitted that one could buy a slimming mirror elsewhere, and when several of the Sharks said it was a con, she tried extolling the virtues of businesses selling more products when women look at themselves trying on clothes in a Skinny Mirror.
"You can smile all you want, but the truth is you're lying to people," O'Leary said. "I'm out, but I also forbid any other Shark from investing in this."
NoPhone, Season 7
In 2014, advertising creatives Van Gould and Chris Sheldon thought it would be fun to create a gag gift with an accompanying website to satirize society's increasingly intimate connections to its smartphones and the antisocial behavior that followed. Their creation, the NoPhone, went from a joke with friends to an actual side gig, and they raised around $18,000 on Kickstarter for their useless hunk of plastic that was advertised as a way to help break a smartphone habit.
The guys are funny, and their satire of companies like Apple is clever, but it was painful to have to watch them go through their pseudo-pitch, for $25,000 in exchange for 25% equity. It seemed as if the Sharks were only slightly in on the joke — and it was never fully clear if Gould and Sheldon were trying to build a novelty gift business or were just mocking the process.
"There's only one thing I hate more than people staring at their phones, and that's dumb patents," Cuban said.
