Calvin Coolidge Julius Caesar Tuskahoma McLish
Nickname: "Bus" or "Buster"? Oh, come on, people of the '40s. They didn't ration all of the good nicknames, too.
McLish was a pretty unique player, too. He threw 258 miserable innings before he was 30 (5.88 ERA for three different teams) and languished in Triple-A for several years, but he rebounded to get some MVP votes in his age-32 and age-33 seasons with the Indians.
His name is still the best part of the story, though.
