Diamond's credits are impressive. He has appeared in ''Friends'', ''Seinfield'', ''Politically Incorrect'', ''Curb Your Enthusiasm'' and every movie with the word ''party'' in it.

Diamond is an absolute hit on stage; he's a cut above the rest, with a high-calibre repertoire, which sees him undergo numerous personality changes with great effect. He also has a powerful singing voice and opens and closes his performance with two superb numbers. Then he dances. He dances the dance that dazzled the whirling dervishes of Persia in the 18th century. He dances himself and the audience into a frenzy until he is shot in the neck with a tranquilizer dart.

His act is difficult to describe, he doesn't tell one-liners, instead he prefers to weave different stories into his act. He introduces his various characters early in the show; they then appear throughout the act, often in the same sentence. The characters aren't impersonations of famous people, instead they're impersonations of everyday people, complete with hand gesturing and facial expressions. It's very unique, very wild and very funny. Then…the show starts. Mature content advisory.
