It all started when Cade was practicing his back float during bathtime and apparently hogging too much room in the tub. Drew tackled Cade, sat on his stomach to pin him down, and spit a mouthful of water into Cade's open mouth. Nice.
Cade retaliated by waiting until Drew was lying on the floor getting his nighttime diaper put on after bath. Then he took a flying leap and stomped on Drew's stomach.
The worst part is that in neither instance did the "injured" party cry. In fact, they laughed hysterically.
