Oh, You Meant That Peace Sign

Early in July, Will attended day camp at Balletmet with a Time Warp Theme. Each day for a week the kids spent the morning across the street at Young Chef's Academy, preparing a meal that they would eat for lunch. Then they trooped back across the street to spend the afternoon at Balletmet, playing games and learning dances that coincided with the decade that was the theme for the day.
On 70's Day, we picked Will up at the end of the day and had the following conversation on the car ride home:

Mom: "How was 70's Day?"
Will: "Good"
Mom: "What did you make for lunch?"
Will: "I made a pizza with a P made out of pepperonis"
Dad: "Why didn't you make a pizza with a W or an S on it?"
Will: "Because it's 1970's Day and the teacher said to make a pizza with a P sign"
