Pies of paper plates and pie tins are a standard delivery mechanism for slapstick humiliation, and for good reason! But I wonder what other things can be used to pile some foam onto before delivering it to someone's face? And how well do they work?

I have a few ideas of my own (parchment paper, lids of containers, etc.) but I want to consult the wide community of experts. I'll be interested to try out a few of your suggestions

I really like a towel full of shaving cream. Definitely one of my favorite ways to get pied, it's big, soft, and gives great coverage.
