In addition to Rochester, Don Wilson, and Dennis Day, he had great supporting players around him such as Mel Blanc, Frank Nelson, and Benny Rubin.
I remember a Christmas episode where Mel Blanc played a clerk in a department store where Jack was shopping. Jack Benny bought a wallet as a gift for Don Wilson, which Mel Blanc gift wrapped for him. Benny kept bringing the wallet back to Mel Blanc to be re-wrapped, with Blanc becoming more and more upset each time. Benny had to turn away from the camera to keep the audience from seeing how he was cracking up because of the way Mel Blanc was carrying on.
Personally, I spent a month in Rancho Cucamonga one weekend.
and arguably the greatest sketch writers and prop men ever.

And the scene alone:
There were several Christmas episodes with Mel Blanc...on radio anyway. One year he was buying shoelaces for Don (couldn’t decide between metal tips or plastic tips). Another year it was gopher traps (lethal or non?)
And Mel as his violin teacher.....
