I watched this show when originally broadcast and searched the Internet more than once for some trace of it.
Here on IMDB it's listed as a "tv special", though at the time I had more the impression that it was a first episode and expected more to come.
The tone was very similar to Laugh-In, combined of course with the usual good-natured comedy of Dom DeLuise. I recall credits being scattered among the bits, and I believe the show was 30 minutes long.
Therefore it went by quickly and the next week I looked for another episode.
Later I searched the Dom DeLuise website the show wasn't included. It would be interesting to see it again if a copy still exists.
