No matter how many times he sings with Elton John, Eminem just can't help being a horse's ass.
Notice around the 3:10 mark where he says, "Tell Lady Gaga she can quit her job at the post office, she's still a male lady." Not that the whole "Lady Gaga has a penis" rumor hasn't been thoroughly debunked already, but "a male lady?" Really?
See today's Quote of the Day for my general feelings on this one.
