Was just watching 'The Lost Hour'
The ep with Nikki from the show "Las Vagas" and she actually says the line "I've always wanted to see Vagas" I thought that was kind of cool.
Sethghecko Out!
That's one of my favorites!
"What's back there, milk and stuff?"
"Cool, huh?"
"If you were Dorothy and this was Oz"
Or the part when the milkman tries to explain to Marshall how he disrupted the space-time continuum, and Mars goes all "Huh?"
