Shatner plugs this cornball LP at the start of the show. You'll notice that his "space gun" is actually an upside down tripod. Also, if nothing else - skip to the 8:50 mark for Joanne Worley's clue.

$20,000 Pyramid with guest David Letterman

Keeping with the Letterman in the seventies theme, here's David on two separate episodes of Dick Clark's $20,000 Pyramid. Two segments from episodes in 1978 and 1979. On the first clip we see him once again with all-purpose celebrity game show contestant Joanne Worley. Check the comments section for helpful details courtesy a friendly reader.

Another clip from a different episode, notice David's striking resemblance to Quentin Tarantino:

The Riddlers with host David Letterman (1977)

As previously mentioned, after moving to Los Angeles and working on his stand-up act every night of the week, David Letterman's next big goal was to break into television. Most stand-up comedians will jump at the chance to do absolutely anything on television when they're first starting out and Letterman was no different. In 1977, while game shows like Let's Make a Deal, The Match Game, and Hollywood Squares were still drawing ratings as high as anything else in the television world - new game shows were constantly being churned out.

As we will see in this pilot episode for The Riddlers, the panel features many stock game show faces. Joanne Worley and Joyce Bulifant were appearing on things like this all the time. History has proven that Robert Urich has done nothing but appear on panels or occasionally host shows with names like "World's Greatest Magic Tricks" during sweeps. Michael McKean probably had the most street cred at the time due to his work on Laverne and Shirley. The opening music we hear is the same tune once heard on the National Lampoon comedy LP That's Not Funny! That's Sick! in which Bill Murray played a clueless game show contestant. This pilot was never turned into a series.

"...will be competing against these five dance instructors..." Bet you didn't see that coming!
