My boss once went to the washroom and there was a spider in the stall. She came out without using the toilet and asked me if I would remove the spider for her.
When DH was in graduate school we spent one summer working deep in the rain forest in Guyana, South America, with another grad student, miles from the nearest tiny town. I started the summer with a mild fear/intense dislike of spiders. The rain forest had spiders a-plenty, especially in the outdoor latrine. By the end of the summer I had greatly less of a dislike just due to having to live with them.
However... one night there was a torrential rain and the little 5' deep creek (that was down a hillside about 30' below our rather primitive camp) filled with enough water to rise over 30' and flood our campsite. Our tent was on a wooden platform about 3' off the ground, and the platform was the only dry spot we could see. We were woken in the middle of the night by other grad student yelling that the water was flooding and that we needed to grab everything that had been on the ground and get it onto the platform before it floated away. So we're doing all this, drenched to the skin, in pitch blackness except for our flashlights and one weak lantern. In the midst of this madness other student shouts to DH that there was a snake - a Fer-de-Lance, an extremely aggressive venomous snake - climbing onto the platform, and that DH should "grab a stick and get rid of the snake." Which DH did so fast he didn't really have time to think about it. Hours later, when the flood began to recede and things were starting to calm down, DH got the shakes just thinking about how close an encounter he had had with such a dangerous creature.
One more animal story from that summer... we woke in the middle of the night to the tremendously loud noise of what sounded like a freight train going right through our tent. After a few breathless seconds during which we reassured ourselves that the tent was empty, the sound continued. We finally realized that it had to be howler monkeys in the forest just outside our tent, but to this day, 46 years later, it remains the loudest sustained sound I've ever heard.
