There are gender differences and this came to mind as something that boys would find amusing while girls wouldn't necessarily see the humor in it. The idea for a tv comedy sketch came to me as I sat down on the toilet wearing my Harley helmut, not seeing any reason to take it off.
The EFS SKETCH
At the urinals,
"Charley, I just saw Billy go into the stall wearing his football helmut."
"Oh no, We've got to get out of here fast"
Charley running out the door being followed by Henry as bits of stall and toilet rocket out behind them to the sound of the loudest fart as Billy flies through the air following them.
Sign: Children remember to wear your helmut when going to the toilet. You never can tell when you may have EFT 'explosive fart syndrome."
