After the funeral, Dick tells Stephanie that her family "isn't exactly Ozzie & Harriet". Lyle Talbot, who plays Cousin Ned, was a regular on "The Adventures of Ozzie and Harriet", playing Ozzie's friend Joe Randolph.
The title is from the 1963 song "It's My Party" sung by Lesley Gore, a number one hit.
During the funeral services George (Tom Poston) tells Dick (Bob Newhart) when Dick dies he'll cry at his funeral. Dick replies politely he'll do the same for George. For which George replies that one of them will not be able. Turns out Poston died in 2007 while Newhart is still living.
