slithy asks: Remember dactyls from "Listen my children and..." or "higgledy-piggledy"?

Higgledy piggledy
Ludwig von Beethoven
Bored by requests for some
Music to hum,

Finally answered with
Oversimplicity,
"Here's my Fifth Symphony:
Da-da-da-dum."

In fact, while I'm not real good at limericks hi Helen I did compose a d-d for the occasion of the first year of this board's existence, back in the good old days. Since I am too modest to go fiche-ing for compliments [ahem], perhaps someone else would like to post it here....
