Well, my avatar is mercilessly stolen from the Dilbert comic strip (it's a slightly modified version of Bob, the dinosaur, a rarely-seen beast most noted for delivering wedgies to deserving co-workers in his office). I like Bob, being likewise large and lumbering, and I like his humour.
My tag line is easily interpreted using any one of the available translation sites (hint: it's in French).
