Good story.
We hospitalized a 95lb Rottweiler tonight, a really sweet one, but every time I opened his cage he bolted and he was really hard to get back in, so at one point I had him by the collar and I reached around behind him to shove from behind and I totally accidentally stuck my finger up his butthole (without gloves on because I didn't intend to need them), so I sort of yelled 'Oh my god, I just stuck my finger up his butt!' and the two other techs and the doctor cracked up and I lost it and just sort of fell on the laughing and ended up sitting in the puddle on the floor where I'd just drained his fluid line, and the dog sort of gave up and just put his face in my crotch and I laid on top of him for a good five minutes just laughing and then I accidentally brushed my bangs off my face with the finger that had been in his butt.
