13. The Samurai
The ultimate explosion of John Belushi's anarchic energy — he waves his samurai sword, he grunts, he screams, he chops up everything in sight. He appears in many different guises — a deli owner, a stockbroker, a psychiatrist, a mob hit man. And he hits the dance floor in "Samurai Night Fever," where his brother gets played by O.J. Simpson. (Oh, those innocent Seventies.) Belushi once accidentally slashed host Buck Henry's forehead with his sword; for the rest of the show, the cast wore Band-Aids on their foreheads.
Best line: "Yeeeeh-aaaaiiiigh!"
