A Funny Thing Happened On The Way To The..., or, Two Completely Unrelated Incidents

I had yesterday afternoon off work to go grocery shopping, the first time off I've had in three or for weeks. Now, I've been in this district for a bit over two years, but the whole time I've been here I've kept pretty much to myself; for a variety of reasons, so I hardly know anybody in the town where I go shopping. I was in the newsagent yesterday and said "hello" to the lady working there, not one of the two ladies who usually take turns operating the place. She said, apropos of nothing, "I'm counting the cards for a stocktake and it's really exciting."
In the next few minutes that lady passed a very important test; I lapsed into my former self and did a two- or three- minute declamatory stand-up routine on the importance to world affairs that the Mungindi newsagent had an accurate estimate on the number of casualties they had taken in the greeting card department. Not only didn't she throw me out, run screaming into the street or even look at me funny, but she even laughed. Loudly. For so long I thought I would have to resuscitate her. Like I said: test passed.
Incident number two: The husband of the Almost Perfect Woman mentioned on this very page yesterday is a vet. About seven years ago he received a call from the local police; somebody had been caught having sex with a racehorse and would he go down to the stables and swab it for evidence?
Several questions occurred to me when I heard this story; As this was the second time the man had been caught with the same horse, was the horse particularly attractive, or did it just put out? Who was the person who caught him and why did they let him finish? Twice? But most importantly, do you think the horse noticed?
