Fun: “Accidentally” mistaking a loose wire for a broken receiver and buying an entire new stereo system so now you can have one on either end of your house and get on-line while listening to really loud music without disturbing the rest of the house.
Not Fun: Knowing you only have fifteen minutes until you are officially the age you said you’d be dead by.
