Rob delivers the final line "I'm no Albert Schweitzer, huh?" as he plays a Bach piece on the piano. Dr. Albert Schweitzer was a medical missionary and received the Nobel Peace Prize. He was also an organist and a Bach scholar, thus Rob's joke. Schweitzer made recordings of Bach pieces which have been reissued on CD.
After the party, Rob and Laura are eating cereal. The brand of the cereal is Wakey Flakeys, the same cereal that Lucy Ricardo and Paul Douglas sold in Lucy Wants a Career. That was from the show, The Lucy Desi Comedy Hour. Both the Dick Van Dyke Show and the Comedy Hour were produced by Desilu Studios.
A point of contention for Laura in this episode is Millie and Jerry insinuating that Laura intentionally left something out of the recipe she gave to Mille for her peanut butter-avocado dip. The recipe calls for peanut butter, avocado, and mustard. Eventually Millie learns from Buddy who tried it that she left out the mustard. In reality the peanut butter and avocado dip was a made up concoction by the writers as no such dip existed.
Laura says that "Without experimentation we wouldn't be on the Moon", and Ron replies: "We're not on the moon." This episode aired years before the first manned Moon landings, but not too long after the U.S repeated the U.S.S.R's prior accomplishment of crashing a probe into the lunar surface at high speed.
