I know he's known for a lot of movies and such, but my wife and I are watching Frasier on Netflix and so that's how I'm remembering him right now. It's kind of eerie - this evening after dinner we were watching the episode Frasier Loves Roz shortly after learning of his passing. That camcorder scene was super creepy.
Anyway, here's to a great character actor who could steal scenes from the stars. RIP Mr. Mahoney.
