Henry Gibson recites "Keep-A' Goin'!" by Frank Lebby Stanton when Rob is trying to decide whether Buddy or Sally should be fired. In the film "Nashville", Gibson's character Haven Hamilton sings a version of this poem at the Grand Ole Opry.
Rob's agent is named George Shapiro. George Shapiro was the manager and nephew of series creator Carl Reiner.
The angry snail Jellybean says to Rob, "Give us a kiss." The gentle marionette mouse Topo Gigio used to say to Ed Sullivan, "Give me a little kiss, Eddie."
Henry Gibson would recite the same poem on Laugh-In.
