I'm re-reading Microserfs at the moment, and came across this particular passage. It made me laugh out loud the last time I read it as well, so I thought I'd share it:

I learned a new expression today: "protein window." Todd told it to me.

Apparently, after you bodybuild, you have a two-hour time window in which your body can suck up amino acids. This is your protein window. I was talking to him and he said, "Man, I'd like to talk some more, but my protein window is closing," and he ran off to the kitchen and ate a chicken.
