when you're home alone & someone knocks on your door: say "who is it?" look through the peep hole open the door crawl around on the ground like a ninja and look through the window very quitely to make sure it isn't a masked murder
"Oh god it must be too late and I need to sleep cuz I made the face and said "phteven" out loud and now I can't stop laughing." - Not my quote, but it was exactly what I did. Most honest LOL moment of my life.
