A man stands and urinates. In a variant of a golden shower, a dwarf stand in between his legs and watches. During urination, the man farts right on the dwarf's head - shocking and surprising the watcher.
I was at Panera, eating lunch with my family. I went to the bathroom and my pesky 3 year-old son tagged along, stood in between my legs, and watched me pee into the urinal. Seizing the opportunity, I completed a Nicaraguan Dwarf Surprise by farting on his head. We both laughed.
