Okay I thought I would give a little history on the flipper/hand scene in the Mos Eisley Cantina. If you read the original script or the novelization of ANH you will learn that Kenobi does in fact slice off Evazan's right arm and he kills both Ponda Baba and Kabe (the small rat/bat like alien). They each got cleaved in half from their head to their groin. Lucas used a wolf man's arm for two reasons. 1) because GL couldn't find a mannequin's arm that looked real enough and 2) back in 1977 GL was worried that a human arm might be too graphic and he was concerned the film might get an R rating instead of a PG. Pg-13 wasn't introduced until 1984, thank you Indiana Jones and the Temple of Doom.

So if you go by the written story Evazan should be the one who loses his arm. But if you want to go by what has appeared on the screen then it's Ponda Baba. I wouldn't mind seeing a human arm, but that's my taste. I'm not picking sides, just wanted to brief you all on a little SW history.
