Sloppy Moe
From Loonipedia
Sloppy Moe is a hillbilly who appeared in Injun Trouble and its remake Wagon Heels. He would go around quoting "I know something I won't tell, I won't tell, I won't tell!" to the tune of London Bridge is Falling Down. When Porky Pig is cornered by Injun Joe, Sloppy Moe reveals that Injun Joe is ticklish and proceeds to tickle Injun Joe with his beard and hands enough to cause Injun Joe to fall off the cliff enough to stretch the entire United States enough to cover the entire area. With the United States colonized, Sloppy Moe then tickles Porky. Sloppy Moe was voiced by Mel Blanc.
In the Tiny Toon Adventures episode "New Character Day," a cartoon called "The Return of Pluck Twacy" has Sloppy Moe parodied as a criminal named "Ticklepuss" (voiced by Frank Welker). When Ticklepuss attacks Pluck Twacy and states that ducks are ticklish in the ears, Pluck Twacy states that ducks don't have ears. Ticklepuss places fake ears on Pluck Twacy and proceeds to tickle them. Remembering what Duck Twacy would to at a time like this, Pluck Twacy subjects himself to pain enough to drive Ticklepuss away.
