[Yoda voice] "mmmm..... Yoda gonna lay the smack down on your roody poo candy ass. Yes." Also I always wondered why Yoda never complained in the movies or anything. I mean everyone else gets lightsabers, he gets a stick. Even though we know Yoda could take everyoe single handed.
Take a look at that link I posted above, it should tell you everything you need to know about Yoda kicking arse.
I read through the whole thing. Interesting. I was lucky enough to see the guy on the Today Show (it was the only reason I watched it I really hate that show), and he seemed to like the new Anakin Skywalker but his opinion is different there. We'll just have to wait two more weeks.
Sorry, I cant imagine Yoda 'fighting'. I can imagine him using the force to whisk away enemies but to actually see him jumping about and using a lightsaber?? It would be like watching an ewok commanding a Star Destroyer
