[Chalky] - I just assumed that the plot outlined in the limerick in question happened in space... :) As for viagra, I thought of niagra (and had a vague idea that there might be an ejaculatory metaphor in there somewhere...) but couldn't think of a third rhyme but hoped others with bigger vocabularies might find one, or else employ a bit of creative twisting to still allow for a fun limerick - so bravo Marc for finding the "gouty pain in the clavicle".

I expanded my vocabulary

When I entered the constabulary   I think we have two limericks on the go simultaneously.

Perhaps three. Shall I ...?
b - I expanded my vocabulary
P - By mimicking old Sweary Mary / S - I'll show that I'm really no fairy / R - When I entered the constabulary
I peppered my chat / Test-os-te-rone / I copped three new words

b+P The barkeep threw up in my sherry
P+S (But then, so do backs that are hairy)
S+R When I slept with the Sergeant's canary.

In my hand is a very strange thing
