A bit off topic, but there is a story about Tex Cobb fighting about a dozen bikers armed with chains and tire irons and winning back in the 80s. They broke his arm and some ribs or something to that effect, but he put em all down in the end.
You can kind of believe it, since this is a guy who took a 15 round beating from Larry Holmes without giving up, in what was apparently one of the most lopsided title fights in boxing history.
Edit: found an article that seems to mention it, or a similar incident.

Might have misremembered some details, or heard wrong.
