Great thread. I was wondering the same thing myself. I often find myself blathering on inanely in OTHER people's threads, but rarely create my own, mostly due to lack of interlect and imagination.
My favourite thread is the one on deviation (not the sexual kind), becuase it allows me to post completely pointless stuff, deviate from the thread starter, and I don't have to try and sound intel, inter, smart.
So, ideas for a thread - got me stumped. How about a thread on, erm, stumps?
