Samuel Michelangelo Rosenbaum, better known as Yosemite Sam, is a Looney Tunes character. He occasionally appears in the Amblin/Warner Bros. cartoons. On Tiny Toon Adventures, he is one of the teachers at ACME Looniversity. On Animaniacs, he has made a few cameos. In "The Warners 65th Anniversary Special," Yosemite Sam recounts his experiences with Yakko, Wakko, and Dot. According to him, they once called him an “itty-bitty baby man”. He took this as a compliment and was very sentimental about this memory. Sam later appears in "Back in Style," being laid-off with the other Looney Tunes and his animators. As a nod to being designed after Friz Freleng, he mentions that he loves the way Friz talks as the two walk out of the studio.
On Animaniacs, Yosemite Sam was voiced by Greg Burson in "The Warners' 65th Anniversary Special," while Jim Cummings took over the role in "Back in Style."
