That's what is so very funny.
TB, the consumate ideologue, old "Rush for brains" and I don't mean "hurry", is standing out there drying off and seriously believing he's outsmarted the entire bar. He knows karate. Broken nose, broken arm, bleeding from most orfices, sopping wet, he absolutely knows karate is the way to go. He won.
'Cause Rush told him so. TB is smarter than anyone else, and he'd pass a lie detector exam. Because Rush told him that, too.
