Years ago, I won a prize in a limerick contest sponsored by Isaac Asimov's magazine. The verse had to incorporate the name of a celestial constellation and deal with the future. I submitted two. This one won me the prize:
An angry young student from Reticulum,
Annoyed at their crazy curriculum,
Said, "They teach biorhythms, Ψ,
And a rational ∏.
I hear Asimov's set to ridicule 'em."
Okay, but I'm haunted by the fact that I've quite forgotten the last line of the non-winner that I also sent in:
Two lusty young lasses from Leo,
Sang together - not well - but con brio.
Their sonorous roars
Caused rents in their drawers,
???
So, I'm offering a prize to the reader who comes up with the best last line... I'll figure out the prize when I get the winner decided...
