"ARTEX! You're sinking!"
Hee hee.
Ahem...anyway...depends on the dancing. For example, I cannot breakdance. I was forced to learn square dancing, line dancing, and polka in elementary school, but I have blocked them from my brain, so I can't do those, either. At least I assume I can't. Both country and polka music make my ears bleed, so I've never had occasion to test my memory retention on those dances.
