I would have used a potato gun!

This reminds me of when my older brother would wake me up for school occasionally he would use the "A-Bomb" I giant water balloon.
Sometimes he would use a Super Soaker, but his favorite was the garden hose. To this day I hate being wet unless I am prepared for it. Ever since waking him up for school, he hates being punched in the nuts...

BAM!
