An old friend of mine (a well known TV actor) used to hold a weekly poker game, before it was all the rage. Being an actor, he loved to pull semi elaborate practical jokes on occasion.
So one day he gets this inspiration, he goes to the store, buys a brand new cat litter box, several boxes of light brown sugar, and a couple of handfuls of tootsie rolls.
He goes home, empties the brown sugar into the new cat box, then takes the tootsie rolls, puts them on a tray, and puts them in the oven to melt a little. He then shaped the melting tootsie rolls into fake cat turds.
Fade out.
Fade in: his friends arrive for the poker game, and there is a full cat box in the corner by the poker table.
As his friends get ready to sit down, he says to his wife: "Honey I thought I told you to remove the cat box before the guys came over? --I'm sorry guys, gimme a sec to get that out of here."
He picks up the cat box, pauses and says to his friends:
"Oh man, that one looks good..." Then fishes out a tootsie roll cat turd and eats it. While his friends were recoiling in horror, he holds out the box and says "Want one, they're good!"
After a beat or two they figured it out, and everyone knew they'd been had by another one of the good old boy's practical jokes.
Tootsie Rolls have never been the same.
