We enjoy watching Shark Tank, but you know what sucks about it? Guest sharks. It's as if the six rotating regulars are not good enough, every few weeks they bring a random one in... and most of them are absolutely terrible.

Betheny Frankel is the worst. Somehow the reality TV "star" was deemed a shark... because she's been on Real Housewives? Can you imagine walking into Shark Tank thinking you'll get a deal with Mark or Lori, but ending up with freaking Bethany?

Then there is a slew of former athletes: Alex Rodriguez, Maria Sharapova, Charles Barkley... Sure, we get it, Charles Barkley was a great basketball player, and star of one of the best sports commercials of all time ("I'm not a role model." Look it up, kids.), so if you want him to be the face of your athletic-related brand, sure, go ahead. But otherwise?

No, the only good guest shark is Kind Bars founder Daniel Lubetzky, whose soulful touch is a welcome counterpoint to Kevin's soulless douchebaggery. As Lubetzky has mentioned on the show, his father is a Holocaust survivor who emigrated to Mexico. If his surname seems familiar, Daniel is a cousin of Emmanuel Lubezki, previously-profiled Oscar-winning cinematographer.

And then there's Chris Sacca, the cowboy-shirt-wearing douchebag who has been accused of sexual harassment multiple times. At least they stopped bringing him back...
