I've never been genuinely bitten by a ball python. Someone else's ball python nicked me, but it wasn't a genuine bite, more of a feint that unexpectedly scraped skin. The only snake I've ever been actually bitten by was a little tiny baby garter snake that I was relocating out of a horse stable so it wouldn't get trampled. It did not appreciate my concern, and was hilariously serious about expressing its objection. Little bugger musked me, too.
