Added some more.
I updated my limericks page with some from the old caustic limerick thread. They are posted under "about Friends". Here's a nasty one I'd forgotten I wrote:
If we root through your thoughts we should find
mainly empties your brain left behind
when it threw in the towel
and crawled though your bowel
to leak out where the sun never shined.
(Gotta love that English language abuse in the last line ;))
