IIRC, one of the voices on “The Real Ghostbusters” was also the voice of Garfield the Cat. He was always wise-cracking and saying stuff kind of under his breath.
I think it changed when Garfield became a full time cartoon, and not just the occasional 30 minute prime time special.
Also, here’s one to get stuck in your head: Gummi bears. . .bouncing here and there and EV-REE-WHERE
something adventure that’s beyond compare
We are the gummi bears
The late Lorenzo Music did the voice of the animated Garfield as well as the animated Peter Venkman from Real Ghostbusters. Interestingly, Bill Murray, who played Venkman in the two Ghostbusters movies, did the voice of the CGI Garfield in the more recent movies.
