When Carson would have his annual "Tonight Show Anniversary Show" in prime time on NBC, the anniversary shows were mainly flashback clip shows, and it was usually the same vintage sketches which got the showcase on the shows (examples being Ed Ames' classic miffed tomahawk throw from 1965, Carson and Jack Webb doing a sketch about "Copper Clappers" from 1968, and John Twomey playing "Stars and Stripes Forever" with his hands from 1974; later anniversary shows would feature stand-up comedians, new sketches and clips from the previous year of "Tonight Show"s). The popularity of the anniversary shows helped lead to the creation of "Carson's Comedy Classics", which is essentially a classic clip show edited down to a half an hour. "Carson's Comedy Classics" showed that there were many other classic sketches and segments that had rarely if ever been seen between the original airing and 1982-1983 (when the show was put into production). Many of the sketches and segments in "Carson's Comedy Classics" have never been released on DVD either.
