After Danny Thomas ended his long-running situation comedy series, he returned to television in a series of comedy-variety specials for NBC from 1964 - 1967. Thomas went weekly with this format during the 1967 - 1968 television season, as The Danny Thomas Hour. Exploring the nature of comedy, Danny Thomas welcomes a star-studded cast of comics and comedians for a series of sketches and black-out gags. The Three Stooges are introduced while making a ruckus in the audience, attempting to move patrons from their seats and "helping someone with his toupee. Arriving on stage, the boys refuse to perform comedy, informing Danny that they've moved on to serious acting and Shakespeare. Later, Moe, Larry & Curly Joe demonstrate a new, unbreakable glass plate to a pedestrian. The Stooges then attempt to assist Martha Raye with her fur coat, and run afoul of a gorilla in the process. Tim Conway's lecture on visual humor devolves into a wild burlesque-style farce, with the Stooges and other cast members running amuck across the stage in a series of sight gags. (thetvdb.com)
