It's begining to sound like a joke store. Do they stock fake vomit? Groucho glasses?

There you go. They're usually found in malls. Back in my childhood, during the Age of Paper, they had a catalog, featuring much of the same stuff that they carry in their stores -- penis-soap-on-a-rope and other high-class goods, along with the fart pillows mentioned elsewhere in this thread -- which were mailed into households where *gasp* innocent children might, and very often did, pick up the mail from the box.
