The can was whipped cream and the fork was to eat the pie, Clark don't be ridiculous what else would he be doing with it?

Except he disappeared into Clark's closet with all of it, and merrily went about filling all of Clark's shoes with pie, whipped cream, or both.

When he came out there was a piece of pie in the pan left, and the fork. That, he handed to Clark. Then he got back in bed just like he hadn't done something he'd have considered immature in a 7 year old.
