The smell of nerd surrounds you

While I was in San Diego at the Comic Con, there was a certain... stench that I smelled maybe 1/4 of the time while walking the floor. Here, in Portland at the Open Source Convention... I am smelling it more frequently. Has no one heard of soap? Also, I've seen 4 women that aren't working for the hotel services, and only one of them weighs less than me.
