"BEHOLD, THE UNDERMINER! I'M ALWAYS BENEATH YOU, BUT NOTHING IS BENEATH ME!"
Ratzenberger really had fun with that role, as did I. It was so short and yet so much fun, totally summed up the campy super villains of yesteryears.
But he's still beneath Hamm.
Not only is Hamm more fleshed out than any of those choices, there's just something about Hamm's indifferent nature that makes me like him, how he treat his life as a toy as indifferent as an everyday man would towards a desk job at the office, how he dismisses things with a snarky line. But I still prefer Mr. Potato Head over him because he's even nastier and snarkier (Hamm and Potato Head are Mean and Meaner respectively), but together, they make for a pretty comical time. For example:
Hamm: Moving buddy? You can't be serious!
Mr. Potato Head: [holding his left arm in his right hand] Do we have to hold hands?
[Mr. Potato Head rearranges his facial features crazily]
Mr. Potato Head: Hey, Hamm. Look, I'm Picasso!
Hamm: I don't get it.
Mr. Potato Head: You uncultured swine!
John's short time in WALL-E also brought a human-touch to the movie. I felt he's a pretty charming character too.
