At 4-5 yo soccer. The best kid by far is totally decked out in cleats, long socks, and shin guards. Fine. Whatever. But, get this. Whenever he bumps into another kid, his body goes totally limp, he collapses to the ground, lies there for 20-30 seconds, and may even curl up and roll around a bit before he finally gets up. GMAFB, kid. You're not fooling me.
