Knowing the population of this BBS, I'm venturing to guess that most of you ate your boogers. Some of you probably flicked them across the room. And I'd say less than 5% of you actually put it in a tissue and threw it away.
Flicking is the best method of booger disposal. Once flicked, you usually can't tell where they land, which means you never have to worry about them again.
Just assuming, boogers smell like the inside of your nose. As to where you might want to dispose of a booger, try underneath your desk.
