When Lucy and Ethel threaten Ricky and Fred to mow the lawn it is learned that the men's full names are Enrique Alberto Ricardo y de Acha III and Frederick Hobart Mertz I. Ricky's name borrows from Desi Arnaz's real name Desiderio Alberto Arnaz y de Acha III.
This episode reveals that the Ricardo's Westport home is just off the Boston Post Road as Lucy ends up driving the lawn mower down it going against traffic.
Little Ricky's dog Fred was played by a Cairn terrier named Danny, trained by Bob Blair and owned by Frank Inn, who also played Fremont in the "Dennis The Menace" series.
