Joel and the 'Bots reaction to the baby oil on Mitchell's nightstand.
Crow: Oh my, my, my, my GOD!!!
"Joe Don Baker IS 'Mittens'!" When you can get that good of a CMOF in the opening credits, you know you're in for a treat.
Just about everything Joel and the bots say is a CMOF, this MST 3 K is award winning.
A slightly more intentional CMOF lies in Benton's interactions with Cummings about mid-way into the film: "You're a lousy/god-damn awful butler!" Especially odd as said "Benton" can be assumed to double as a full-on cop-beating henchman.
Even better is the way Benton argues back like a petulant kid.
Everything in the initial sequence, from Johnny Mathis invading Deaney's den to the line about "Oh there is? I just thought there was a big slob walking around my house."
