I saw this one the other day and loved it. Bart can never resist some kind of prank when he calls Moe. He was supposed to be asking for his dad, and he asked to talk to Homer Sexual. Since Moe figured out eventually that Bart's the one whose been doing it, they should either here him do them in tree house specials every Halloween or her Moe get a permanent case of amnesia where he doesn't remember that it's Bart.
Take care and God bless
