How about on eof those swirly paper hats that were famous in the 80's.
You know they come flat and you push out the middle and it opens out into a paper cap.
Think Wimpy Burger places used to give them away when you had a party.
...ahh the memories.
Anyway, they're sooooooooooooooooooo cheap and nasty - that's the 583 hat, mmm'kay
