'Shark Tank' Preview: Mark Cuban Calls BS on One Entrepreneur

One entrepreneur really fails to impress Mark Cuban in this week's episode of Shark Tank.

The man, from Cumming, Ga., pitches his unique exercise clothing that provides hypergravity weight training. Cuban admonishes him to give scientific data — and not anecdotes — about why his clothing works, but he doesn't believe what he's told.

"My BS meter is going through the roof," Cuban says in this clip, which is exclusive to The Hollywood Reporter.

Shark Tank airs at 9 p.m. Fridays on ABC. The episode also features a Spokane, Wash., entrepreneur with a product to appeal to today's "urban beardsman" with beard oils, mustache waxes and a community for facial hair aficionados; two New Yorkers with a karaoke machine that adds vocal harmonies to help users sound like their favorite stars; and a St. Louis woman with belts that are designed to be easy for kids to buckle.
