Jesus! Literally. An appearance in some versions of the Talmud, but not all, as these passages were excised by the Jews -- in this case, as the known teacher of a student who has an encounter with Rabbi Eliezer -- which becomes relevant as he tries to figure out why he suffered arrest for heresy by the Romans. Also, the story of Hanina ben Teradyon (more than a Who's Who) - the passage that recounts what happened to him when he was arrested by the Romans and then killed by them.
