I know it's in the Original Post, but "Terry Tate Office Linebacker" makes me cry from laughter every time. Here's the full "episode" Also good is "Vacation"
This commercial is fucking retarded, and yet, as a kid, I couldn't get enough of it. There's something bizarrely funny about it.
Emarald Nuts has several great commercials, but their Superbowl ad from a few years back absolutely kills me with its weirdness.
"I'm good." First time I saw it, when the golfer says, "I hooked it," I thought he was saying, "Ah, fuck it."
