Quote from Chandler in The One with Joey's Porsche
Chandler: Check it out. When the babies wake up they can meet Krog. Monica: Chandler, what are you doing? That thing could poke someone's eye out. Chandler: He can do more than that. He can destroy the universe. Phoebe: No, Chandler, they could swallow one of those little parts. And also, look at his smooth area. That's just gonna mess them up. Chandler: They're not going to swallow anything. You guys are being way too overprotective. When I was a kid, my mom used to just throw me into a pile of broken glass. Phoebe: What? Chandler: Glass, sand, whatever.
