There were 5 great jokes in the first 30 seconds; amazing! Free radicals, "present!", smog rating, warcraft, staring at the sun. I'm surprised, though, that they didn't jump on the name Mikey O Conner with a John Conner reference.
Lots of other good jokes: Scrappy Doo, "That's not my pack," "I could still slap you if you wanted," "Did you just order breakfast in the middle of this cutscene?", "I just had a really long blink," "I'm declaring this a boosh-free zone," "I had another minor stroke there," "A toast to freeing the hearts and minds from the bodies and heads in which they are currently enclosed."
