At around age 6 or 7, I asked my parents about leap year... They gave me some fake explanation, and then proceded to screw with my head by telling me all about "Leap Birthdays"... They told me that once in a person's life time, you get to take a leap-birthday. By doing so, you got twice as many gifts, but none the following year. They also noted that people usually save their leap-birthday for when they turned 16 or 18, in an effort to obtain a car. Keep in mind it was only a couple weeks away from *my* birthday.
About a week later, I approached them... "Mom, Dad, I've given it a lot of thought...and I've decided to take my leap birthday this year. There's a lot of gifts I want this year, so I think it'll work out."
My parents didn't stop laughing for quite some time...
