It's HOT outside! At least it is already in many parts of the country right now.
This Saturday, why not plan an old-fashioned squirt gun fight in the back yard? Toss in some water balloons. Or set up some targets and don't stand to far away when you shoot / pitch at them.
Oh... and one more thing: Why not hold this shooting gallery in your birthday suits? Sounds like fun to the Platypus.
Go on. You still have time to stop by the store and pick up your H2O arsenal.
Have fun! Play naked!
