Untainted by aikido, sure. Untainted by sitting on the couch watching MMA and believing that having a Y chromosome means they know how to fight, perhaps not.
That's always a fun night. Some favorite quotes that have come out of that sitch...
"Hey! I cant catch your kicks like I do in karate class!"
"I wasn't ready when I attacked you!"
"No fair! I thought aikido didn't have that. You cant do that!"
"OWWW! Whoa, what the hell did you just do to me?"
and the best
"How come I fell down? Do that again!"
