Eventually, every male child will play “Old Faithful” and launch a geyser of pee into the air, usually while flat on his back. After much trial and error, I found the best way to combat this.
Get a stack of paper Dixie cups and some tissue. Take one cup, wad some tissue into the bottom and place it within reach. Now, when Jr. lets it fly, quickly grab the cup and invert it over the stream. The tissues will soak up the pee and you’ll stay nice and dry. When the performance is over, simply toss the cup into the trash. Set up the next cup and you’re ready for the encore.
