This reminds me of a certain quote by Christopher Lee...
"Someone asked me yesterday if Dracula met Saruman and there was a fight, who would win.
I just looked at this man. What an idiotic thing to say. I mean, really, it was half-witted."
-Christopher Lee
And that said, I agree, Gimli can outfight, outdrink, and outcool that sorry excuse for a dwarf.
Even with the fake beard, though... After Snails' death, that dwarf was the best thing in the movie.
