Endorphins are crack

There are some things that inevitably happen on my way home from the gym all hopped up on endorphins. A certain song like Gloria Estefan's "Conga" or the Bee Gees "Staying Alive" comes on and I find myself, more than once, bouncing along in my seat and dancing as much as I can while working the steering wheel and gas pedal. Sometimes that just means rocking back and forth while spastically shaking my shoulders. It's fun. Then I start to think crazy things like "Does anyone know what the guy is saying before the chorus before he says 'Staying alive, staying alive'?" I usually just mumble and say things like "Na na na na na na na na na na na staying alive, staying alive... I don't think anyone really knows. Except Mr. Bee. Or Mr. Gee.
