Hours of creative fun
Where does that "dum dum duuuum" thing come from? Was that exact musical interlude ever used in an actual movie? Maybe it is one of those weird pop culture imaginings, like "Play it again, Sam," or, "Alas poor Yorrick, I knew him well," or, "Frankly Scarlett, I don't give a gosh darn heck."
Somebody needs to worry about these things, and since the Department of Asinine Suppositions is overloaded already, I pass the buck onto you all.
