As strange as the whole scenario would be, I would actually have to tell my kids that they
couldn't take a peanut from the weird man, since my stepson is deathly allergic.
We dressed my (hugely plump... or "sturdy" as my friend likes to call him) kid as a sumo wrestler.

Unfortunately all of the posed photos got ruined by blurriness and a messed-up flash. But here's one in his carseat before we left the house for the Halloween party. He had a little bathrobe on to keep him warm in transit, but you can see the sumo-diaper and little topknot.
