Joey: (to Monica and Chandler) Hey, hey listen... What do you guys know about investments?
Chandler: How come?
Joey: Well, I'm starting to make good money on the show and I'm thinkin'... I should probably do something with it.
Monica: What do you do with your money now?
Joey: Well, it's taped to the back of my toilet tank. (realizes he just gave away a big secret) I didn't say that! It's, it's in a bank guarded by robots!
