OK, this one we can do..... from BOTH sides of the pond.
About 19 years ago, during a very lean time, a very good friend of mine took on a remodel of a rental house for a business acquaintance. He asked me to fresh up the wiring, after which, finding out I had plumbing skills as well, asked if I would assist in replacing the old piping as well.
This was at the outside edge of a landfill, in a low lying area.
We were crawling under the house in a crawl space about 18", he had told me to "take it REAL slow" as I went ahead of him with copper tubing and a torch. I should add here, for clarity, that both of us were shooting competitively at that time.
I'm crawling on my back, checking out the plumbing in the joists above. He says "George, don't move". We're both wearing coveralls as it's pretty dank and moist under here, and we know each other well enough that when he said "Don't move" I trusted him.
I can see, dimly in the light, that he is reaching inside his coveralls, and retrieves a 9MM pistol.... OK, NOW I'm worried!!!!
He takes aim TOWARDS ME, and I am deafened for several days. I asked him... calmly (and if you believe that...) what he was doing. He pointed behind me, I looked around to see one very large copperhead coiled up... and now deceased.
Knowing these poisonous little ropes are very familial, I decide the plumbing under the house is fine, and needs no further repair.
And having crawled in nearly every hole in the District of Columbia (let's not forget the Pentagon fairly recently) I'm not even gonna START with Rats.
