The Fart Filter: A Flatulence Filtering Prank
The Fart Filter makes the perfect prank box for any occasion.
The Fart Filter prank box is one of many absolutely hilarious, yet just plausible enough to set the hook. The professionally laid out design resembles an actual cheesy TV infomercial product.
In case that fails and they are just overly anxious to filter their farts, they will be relieved once they see your unique gift inside. If they are not relieved to find this to be a prank, you probably need to reevaluate your relationship.
