Well, i always name my pieces. There names are Bosley, Charlie, Mary Kate, and Ashley. (Although Mary Kate broke and started pissing all over the place.)
I've never been able to think of a name that I was completely happy for any of my pieces. But if I ever buy a mushroom piece I'm gonna name it Art Garfungal.
I named a small bong of mine "Friend", sometimes referring to it as "Junior". I sometimes call a glass black pipe "Merlin". It looks like a Sherlock Holmes pipe, only it's glass and completely black.
I always name them then forget the name then make a new one up... then forget it and the cycle just goes on and on and on. I call my bubbler "The Love Doctor". That's about it
