Yosemite Sam is a cartoon character from the Looney Tunes and Merrie Melodies series by Warner Bros. His real name is Aloysius Bartholomew Sam, and he is commonly depicted as a mean-spirited, aggressive gunslinging cowboy with a short temper and a strong hatred of rabbits, especially Bugs Bunny. He appeared in over 30 animated shorts, often cast in various roles such as an outlaw, pirate, king, and more, with his classic black mask symbolizing his outlaw persona. His loud temper, colorful insults, and various aliases are core to his character. Regarding the phrase "What in tarnation?," although many people associate it with Yosemite Sam due to his fiery Western character, he surprisingly never said this phrase in any original classic Looney Tunes cartoons from 1945 to 1964. This is a common Mandela effect, where people have a false shared memory of him using that phrase. Yosemite Sam did say "tarnation" in a few more recent Looney Tunes episodes from around 2012 and 2013, but it was not a staple catchphrase in the original cartoons. So, while Yosemite Sam embodies the spirit of saying "What in tarnation?" in a Western style, this iconic phrase wasn't really part of his original classic catchphrases. Instead, he was more known for shouting things like "Great horny toads!" and calling Bugs Bunny names like "varmint" and "galoot." The association with "What in tarnation?" is mostly a modern or cultural memory artifact rather than an original character trait. This explains why "What in tarnation?" is often humorously linked with Yosemite Sam, despite its absence in the classic era cartoons.
