Ep 7. John Davidson (guest host), Dom DeLuise, Lily Tomlin

John Davidson takes over as guest host as Johnny Carson takes a night off, and he welcomes two comedic legends to the couch: Dom DeLuise and Lily Tomlin.

Davidson kicks off the show with a monologue that pokes fun at everything from airport security to the recent trend of disco music. He then introduces his first guest, the always-entertaining Dom DeLuise. DeLuise regales the audience with stories of his time performing with the legendary Mel Brooks, as well as his experiences on the set of his latest project, a new comedy film.

Next up is Lily Tomlin, who charms the crowd with her quick wit and signature brand of humor. She shares stories of her early days in show business, including her time working alongside another iconic comedian, Richard Pryor. Tomlin also gives the audience a sneak peek at her latest one-woman show, which is currently touring the country to rave reviews.

Throughout the episode, Davidson keeps the laughs coming with a variety of skits and segments. In a bit entitled "News from the Future," he imagines what the world will be like in the year 2000, with hilarious results. He also sits down with a group of kids to get their take on current events, leading to some amusingly offbeat responses.

As always, the musical guest is a highlight of the show. This time around, it's the popular disco group Chic, who perform their hit song "Le Freak" to the delight of the audience.

And of course, no episode of The Tonight Show would be complete without a visit from the beloved Carnac the Magnificent. In this classic bit, Carnac uses his psychic powers to predict the punchline to a series of jokes, leading to some uproarious moments.

Overall, it's a fun-filled episode that showcases the comedic talents of some true legends of the industry. Davidson proves to be a worthy guest host, holding his own alongside his esteemed guests and keeping the audience laughing from start to finish.
