Is that quote from The Fly? I recite that quote all the time but had forgotten where it originated.

I DO remember a trailer for The Fly II, which I can never find online, but went like this (to the tune of "Hush, Little Baby" with music box accompaniment and a super creepy male singing voice):

Hush, little baby, don't be sad;
you'll grow up to be like dad.
Hush, little baby, don't you cry,
just because your dad was... the fly!

Cheers,
Michelle
