I've been bit many times by both babies and old adults. Sometimes I don't even notice it until I see a little drop of blood on my hand. Ball python teeth are very sharp, but they're also very short and don't penetrate the skin very far, usually you can't even tell where you've been bitten after a few days.

Got a nice bite last night as a matter of fact. I was feeding all of my sub adults and one of the mice got squirmy and I accidentally dropped it outside of the snakes tub. I reached over to pick up the mouse to get it in the tub and the snake, smelling food, reached out of it's tub and tagged me. I just thought to myself, Hmmm, that was kind of stupid... Then I washed the blood off my hands and then went on to feed the next one.

Bloodiest bite I've ever received was from my Cat when I was trying to restrain her for the vet when she was in a lot of pain. No stitches but I probably should have had one or two.

Most painful bite I've ever received was from my Shetland pony when I was a kid. I ticked him off one time and he swung his head around and chomped on my leg. No blood but a nice painful bruise. Snake bites are NOTHING in comparison.
