My nephew must've been about 6 years old when a friend of ours stayed over for a while. This guy had some serious sinus problems and used the old method of keeping a tin of snuff available at all times and using it periodically. One morning while this guy was taking little pinches of snuff from his tin and sniffing it my nephew stood staring at him with a confused look on his face. So this guy gets a grin on his face, holds out the tin and says to my nephew, "Do you want some?" my nephew looked totally disgusted and said, "No thanks, I put mine in a tissue!" :-)
