What's the best prank you ever got a loved one with on this day?

Back when I was about 8 or so my mom and my older brother and sister and I set the clocks ahead several hours. We, three kids, then faked like we fell asleep in the living room while my mom went and rushed my dad into getting ready for work because he was "late"! His shift has always been like 11p-7a so it was dark outside and everything. [Big Grin] He was about to rush out the door when we finally stopped and told him. It was soooooo funny. My daddy was a very good sport about hte whole thing and even managed to get us back later.
