True story:
We're at SeaWorld Orlando, walking on this wooden bridge across some big lagoon after watching the killer whales show, and there's this Cleaver-esque family in front of us - Mom, Pop, ~10 year old son, 4-5 year old son; younger son is holding onto mom and dad's hands, but wait...he lets go of Dad's hand, reaches down the back of his pants - nearly to the elbow, performs some mysterious operation, takes out his hand, smells it, and grabs back onto Dad's hand. We all bust out laughing and going "Stinkpalm!"
The family turns around, looks at us, and promptly moves to the far side of the bridge, picks up their pace, and keeps a wary eye in our direction.
All in all, a small price to pay for the smiting of one's enemies.
