Yes. I have been bucked off fast little demon ponies five times -

Well -

actually, only one of them was a buck. The other was a sudden turn at a gallop, the other was falling foward over a horse's head on a hill when she spooked, the other was a sudden turn after a jump gone wrong, the other was a spook.

And then, when I was little, I fell off a really old pony because I was seven years old.

Well -

The worst I've ever gotten myself hurt is just getting really scraped up and bruised, so ^^

I'm pretty sure le cousin got stomped on, though, if I remember correctly -

so that's a serious ouch -

I've had a horse stand on my foot-

Yeah, it's not real fun. As long as you shove them off as quickly as possible, it won't do too much damage.
