'The Dick van Dyke Show'?!
Holy crap, I never thought that iCarly would show a clip from The Dick van Dyke Show!
In these scene, Carly is in the bathtub, I think preparing for a date, and she watches TV, in which a classic scene from The Dick van Dyke Show plays (Episode: "Never Bathe on a Saturday"), where Laura Petrie gets her toe stuck in the faucet; Carly laughs it off, thinking it's impossible for something like that to happen, until it happens to her as well.
I started watching Dick van Dyke last October, when TVLand aired a marathon for its 50th anniversary; I never would've thought that iCarly would borrow one of their jokes like that!
