And that's exactly the reason I never liked the show, it's the same old, shitty stereotypes. This show masks its mocking of geeks and nerds by making them main characters and adding more detail to their interests.
Other than that, it's the same misogyny and lazy jokes that rely on the laughtrack to work at all that you can find in 'Two and a half men'. Yeah, Tigerblood Charlie Sheen was right, Chuck Lorre is a hack.

Most martial arts are simply too specific for MMA (Teakwondo for example), and Aikido is certainly one of them. That's why many MMA fighters train in Jiu-Jitsu, it's a grabbag of techniques.
Aikido is great with throws, joint-locks and evasive moves but that's mostly it. There's no emphasis on kicking, punching or holding techniques. An Aikido-practitioner won't choke you out, he or she will break your shit. Bend your joints in ways they shouldn't or straight up break your arm. You can't unleash that in a ring where people go to earn money. No matter how many punches you can take, how many throws you can recover from, a broken wrist will end your fight. And then you're out of a job and training until it's healed for a couple of weeks.
Aikido is not flexible enough to be effective and too damaging once it can be used for full effect.
And it does work in real life, it's just the conditions for success are far narrower than with other, more versatile martial arts. That's why Krav Maga works so well in real life, it just goes to what causes the most effect. So a lot of ballskicking. And punching. And Kneeing. All the balls, all the time.

I'm a big fan of EC-Comics-style ironic punishment and I love the Punisher and other revenge fantasies but Bill is right. You have to be better than them. You can't sink to their level, you need to keep your ethics in place.

But it's of course A-ok to kill Nazis once they do actual physical harm to others. I am a big Indiana Jones fan too, you know.

I'd downvote for the sexism but the lady's skill is to great for that.

Cthuluh's doggie?

The Lord said 'Basta'?
See, that's why I'm an apatheist, because a simple letter can make that much of a difference when it comes to your importance in my life.
I'll have my Spaghetti and I'm gonna eat them, too.

Proves my point: Japan is like King Midas, just with WTF instead of gold.
