My niece and her daddy were running errands and ended driving by  DPS (Texas Department of Public Safety) field. It was full of these cops-in-training practicing hand-to-hand combat...  They were totally getting after it;  they had martial arts gloves and boots on, and were all muddy and grass stained, and basically throwing down en masse like in some Bruce Lee movie.

Emily asked
"What's those mens doing?"

Her daddy replied "Those people are police, and they're practicing how to stop bad men.  Like Spiderman or Batman does.  They're practicing how to make bad men stop doing bad things."

... long pause ...  and then in a voice as solemn and definitive as a judge:

"No Daddy, i think... i think... i think thems are doing *yoga*."

It was so damn funny he almost cried!

 Nothing like doing yoga while taking someone down!
