I wish they'd made Walter more of a recurring role instead of just appearing in 2 episodes. He was hilarious.

I also wish they'd kept Kenny on for more than one season. I know he was just a kid, but I liked him. He could have been like Radar on MASH.

Was Walter one of Lowell's rat shooting buddies?

I think Walter was the air traffic controller....

Yeah, he was the air-traffic controller.
