Dennis the Menace (character)

Dennis the Menace is a troublemaker.

History
When Sideshow Bob was after Bart, he asked his family who'd want to hurt him, as he is just this century's Dennis the Menace.

Bart was talking with, the original Dennis the Menace, when he was in Greaser's Cafe.

He was seen on the cover of The Bible for Wise-Asses.

When Bart wondered who he was, Dennis was at the school's playground.
