Heh heh, maybe they should just replace Mickey with Rickey Rat:
R-I-C
See you in the sewer, suckers.
K-E-Y
Why? Because we're vermin.
R-A-T!

For decades, a widespread rumor claimed that one night Uncle Don had inadvertently spoken into an open microphone, saying “There! That ought to hold the little bastards.” However, this has been debunked as untrue. The rumor was later resurrected in the 1950s, when an audio recording of the mistake turned up on a Kermit Schaefer Bloopers album, though this was later shown to be a fake recreation. (Some sources, such as John Dunning’s Encyclopedia of Old-Time Radio, claim that Carney always denied the rumours; others say that he actually admitted the gaffe to friends, even though he knew it never happened.) Ultimately, this became attributed to later children’s shows as well.[2]
