What's Worth Watching: Shark Tank Goes Out with a Flash

Shark Tank, "623" (Friday, May 15, 8/7c, ABC)

GoPro founder Nick Woodman guest-Sharks on tonight's season finale. There's a cat lady who has an idea for a cat café and a pair who claim to have reinvented the wheel by turning it into a cube, which is certainly an…interesting…idea. But just because he's a guest, don't expect Woodman to go easy on the pitchers. (If you need a fix after tonight, but before new episodes return in the fall, reruns are just about everywhere these days)
