There's an ad with both Garfield and his creator, Jim Davis in the early or mid-2000's that does with The National Commission on Writing, which part of the College Board. Garfield and Jim Davis have been in two American Express commercials together in the 1980's. This one is more educational and non-profit saying that "writing is essential" that every comic strips, video games, TV shows, movies and hit records begin with a writer(s). Garfield is pretty much voiced by Jon Barnard in this ad. Jon Barnard did the voice of Garfield in video games and commercials after Lorenzo Music eventually passed away on August 4, 2001 from bone and lung cancer.
