I believe the cartoon is entitled **Bewitched Bunny**. Unfortunately, I don't have a video describing the scene.

In short, Bugs Bunny (dressed as a truant officer) shows up at the witch's house who is fattening up Hansel and Gretle. As the children are engorging on the dessert, Bugs asks the children what their names are. When Hansel says his name, he exaggerates the vowels.

Bugs then says "Hansel?" to himself a few times in confusion.

Why is Bugs confused by the name Hansel?
