Loved that show. Fun fact, Lorenzo Music voiced Garfield in Garfield and Friends, and then Peter Venkman, Bill Murray's character, in the Real Ghost Busters. Murray went on to voice Garfield in the CGI movies. Bonus Fact, after Music left The Real Ghostbusters, Dave Coulier, of cousin Joey (Full House) fame, took over the role, doing both shows at the same time.
In Zombieland, Murray said Garfield may be his only regret. (Love that movie; Zombieland, not Garfield)
Also Lorenzo Music regularly volunteered at a suicide hotline and callers would sometimes recognize his voice. "My wife left me, I'm broke, I have an incurable disease... Hey did you know you sound like that cat on TV?"
A bit late to the game here (sorry!) but the birthday of TF2 (and the Orange Box) makes me feel old. Even though I didn't start playing TF2 until 2013, it still feels like it's been with me for a long time. Definitely one of the most rewarding fan communities I've had the privilege of being a part of... in fact, I can't really think of one that tops it offhand... Here's to many more years
