Reading the booger blog reminded me of a story my aunt told me.
My cousin Hunter used to suck his thumb, and if he liked you he would hold out his thumb and let you suck it too.
One day he was sitting in my aunt's lap while they were watching TV. Hunter was sucking his thumb and my aunt was immersed a movie.
Hunter held up his thumb and said, "Look Mom!"
So my aunt said, "Thank you honey, num num!" and bent over to suck Hunter's thumb.
Hunter said in a horrified voice, "Mom, it's a booger!"
My aunt pulled back to look at Hunter's thumb and saw a huge booger on the end.
