If you ever pulled a prank on my dad, you'd better have your running shoes on and a huge head start. I remember the water gun and water balloon fights, hide and go seek, and all the motorized gadgets that I managed to "somehow" get dumped off of. I'd end up getting thrown in the pool, chased through the yard or sprayed with the garden hose.
When family and friends visit he'd chase the kids with a vacuum cleaner - they thought it was great and remind me of that every time I see them. I don't think my dad realized that he had daughters - we would help him split wood for the fireplace, reel in that monster bluegill, or ride around on the tractor. Although, he never did seem to mind when he'd wake up with 100 barrettes in his hair or his fingernails painted.
Being a kid at heart and not to take myself too seriously are two of the great qualities that I learned from my dad. He could make watching paint dry fun. At my dad's funeral the kids we used to play with, who had their own kids said to me, "I loved your dad. He was always so fun - remember when he used to chase me with the vacuum cleaner?" Many of my dads' friends had similar stories, like the headlights on their car being rewired to their horn. I love my dad, his memories still make me laugh and I miss him every day.
