Wally, you prove, as I've tried to demonstrate myself more than once, that limerick can be used to say almost anything, serious, funny, heavy, light, nonsense, informational. I've even used them to write a critique or comment on someone else's poem... though we can't do too much of that, ya know. It can get out of hand, especially with limericks.

P.S. Note that you have a couple of
run-ons in the group. Very unlike your carefulness!
