Bats are quadrupeds. When they walk they walk like a pterodactyl with the elbow of the wing. They don't stand on their hind legs. See the vampire bat.

The person you queried mentioned "intentional goading." Which is what you're continuing to do with that Calvin and Hobbes link. I think this, the flag and accusing me of trolling is taking it too far. A little goading is ok during a debate, I returned the goad (which I shouldn't have), but ultimately I didn't have a problem with it. I think, now though, it has escalated now past the point of no return. I think I'll be exiting this thread. Farewell.
