Some funny stories here! My is embarassng. Taking the new mare out for our first ride, eery exciting! (She was broke but had a year off before I got her--I'd never even ridden her around the pasture, this was actually our first ride ever together.) Anyhow, saddle up and off we go. Walk half way to the neighbour's house and decide we're ready to trot...wheeeee! I'm having a blast, she's just wonderful! Get to the neighbour's to meet my riding buddy and find that her Dad has company--a group of ranchers and horsemen standing around the arena. One walks over chuckling. "Nice horse," he says, "but what's the point of having a cinch?" There was about four inches of daylight between the cinch and her belly. Oh my gosh, I wanted to crawl under a rock and hide.
Lesson learned (and really, I had been taught this lesson before)...tighten the cinch, walk for a moment, check it again. Heck, check it once more after you've ridden for ten minutes. LOL
