There is a very funny one on TV now where I live.
Two samurai are in a standoff, with swords held aloft, on an old dirt road. It looks cold. The wind is blowing and the trees are bare as they stare at each other from four feet apart, waiting to see who will make the first move.
One twitches his nose a little, then lets out a big sneeze. The other attacks since his eyes are closed as he sneezes and the video stops just before the sword reaches his neck.
The product? Contac cold medicine.
