Breakfast of Champions

This morning my mom asked Victor what he wanted for breakfast.

"Mushrooms!" he replied without hesitation.

A few minutes later she tried again. "Anything else?" she asked.

"Nope," he said.

Then he went to get the box of Lucky Charms, which happens to have a picture of a mushroom on the back. That's a less-funny punchline than wanting actual mushrooms for breakfast, but it does make more sense.
