This story out of the Peoples Republic of China prompted a little brainstorm that would fit in with Day By Day cartoon I think. So here goes.
Zed, Damon, Jan, Sam are in a supermarket shopping, commenting on high food prices. They get to the produce section and Damon looks over the watermelons on sale.
Zed, "Careful that watermelon might come from China."
Damon looks confused, "What?"
Jan, "Aren't you stereotyping Zed?" She reaches to touch one of the green striped watermelons. *BOOM*
Sam checks on the twins who are hiding behind her before commenting. "Trust the Commies to make an IED melon."
