In high school I was with the two hottest girls in my history class working on our group project (awesome luck).
We were huddled over our paper and I scratched my nose. On cue a booger came out and landed smack dab in my middle of the page.
I went beet red and in my head I asked God to strike me dead. (He didn't). They laughed and one of them took a kleenex out of her purse and got it. In retrospect those were some chill girls, they never told anyone what happened but I was mortified.
