Ditto. I think people see the muscles and think that and the weird speaking patterns are all there is to Thor. But he was able to explain the stories of Asgard to Jane and connect them to her work, so I think he's fairly intelligent if a little brash and paling beside Loki. Most people can't contend with Loki, so that doesn't mean he's stupid. I always wince when I see people writing him in all caps and with absolutely no idea of what's going on.

Baffled Thor is fun to play with though. <3
