Sesame Street Themed Party and Need Ideas?

Put it in a giant foam cookie!!! Just grab some polystyrene, cut it circularly, and hollow out the middle a bit. Stick the shirt in there, and close it up. (Seal it if you want) Decorate the top with some brown crepe paper, and voila, you have a cookie stuffed with a tee shirt. (And maybe a thank-you note inside for the parents)
