I saw that episode earlier tonight on ABC Family, in that teaser, Joey told Michelle to play "Knock, Knock" jokes. After Joey took a "Knock, Knock" joke, she was saying "You Got It Dude!" as seen on that screenshot I have on my avatar. This is how it looked like.

Cute pictures. "You Got it, dude" was my 2nd favorite Michelle quote. My favorite Michelle quote was "You're in BIG trouble, mister!!"
