When my son was born we called him Gas-man occasionally (mostly on the occasions when he was expelling gas of some sort - most of his waking hours). So, when my wife, son (now 16 months old) and I started caching together, he got to be the inspiration of our team name. Kind of lame, but we like it and are sticking with it. However, when friends come along, I'm not sure that they like being lumped in with us dorks... Anyway, interesting thread.
