This program had a great run for around a decade with so much comedy packed into each episode, but what proved successful ended when Rick got married and they brought his real wife Kris onto the show in the 12th season. They would have been better off casting a professional actress to play the part. Rick and Kris did not have the onscreen chemistry as a married couple, unlike Dave and June who were affectionate and doted on each other.
The only ongoing comedy they had left was keeping Wally (Skip Young) as a college student for almost 10 years. He started as Dave's fellow fraternity brother in 1957 and was still going to school in 1966. Skip Young was well into his 30s by this time and looked too old to play the part. Aside from this, the show pretty much dried up by the last season, old gags no longer worked, and hence was the end of what was one of the best sitcoms of all time.
