Perfectly timing a microwave beep so it doesn't go off. "I don't know why I feel like a spy every time this happens. You're standing there, intensely watching the numbers count down, waiting until it hits '1' so you can stop it in time. When you nail it, it's like you've outsmarted the machine. Also, it's way more satisfying when it's at night, and you're trying not to wake everyone up."
