Snots.

We all do it! Only some are brave enough to admit it! Sometimes a tissue just isn't enough to take out them hard scabby ones. In that case your finger has to go in, pick around and extract the boggie.

Why is that disgusting? I mean I see the more practical side to it! Well yeah as long as you wash your hands after the exploration  I dont see the issue at all! But then I am one of those guys who feels a sense of accomplishment after a fart that smells a little.
