What episode was it where Bart says "Were there any Oompa Loomaps?", to which Homer replies: "Yeah, but he wasn't moving."
We couldn't figure it out for the longest time. It was bugging us Simpson fanatics all out.
It's always great to quote the Simpsons though.
Turns out it was the sugar-addiction episode (Sweets and Sour Marge). And the quote isn't verbatim. Besides, Homer asks Marge the question, not Bart to Homer. Thank goodness to have the internet to set us straight. (I know it's cheating - but better to have one's facts correct than spreading around lies.)
