I just saw Twister for about the fourteenth time, and I think Perl is Philip Seymour Hoffman's character in that movie, what was he called, Dusty?

He's a hippie-looking guy who's not quite normal, barreling down the road listening to classic rock in a battered old truck full of battered old equipment, but there's no question about his ability.

He might not be the guy you take home to meet Mom, or to work to meet the Managing Director, but, you know, he gets the job done and you feel a great affection for him.
