I saw a good cartoon the other day. 2 naked men from the waist down, one peeing on the other. Caption "No pants, you get wet legs". Next frame had one of the men in pants while the other peed on him. Caption "Wear pants for some protection". Next frame both were wearing pants and one had a wet stain down the front. Caption "Everyone wear pants for even better protection". Final caption, "Now do you understand the point of masks?"

I liked it anyway :-)
