Other episodes with at least one bleeped out f-word: "Mac and Dennis: Manhunters", "A Very Sunny Christmas", "Mac and Charlie: White Trash", "The Gang Gets Analyzed", "Charlie Work", '"The Gang Tries Desperately to Win an Award", "Mac and Dennis Move to the Suburbs", and "McPoyle vs. Ponderosa: The Trial of the Century".
Dee similarly worked "wacky" sound effects into her comedy act in the Season 9 premiere The Gang Broke Dee.
The Season 8 DVD special features has the original "Lady House" (along with a talking cat.)
We saw Mrs. Kelly doing things in threes in the Season 6 episode "Mac's Mom Burns Her House Down." In that episode, she explains she does it "so Charlie doesn't die."
This is the 2nd time in the series that Dee is seen wearing a neck brace at the end of an episode. The first time was back in season 2 in the episode "Charlie Gets Crippled."
Dennis is the only member of the gang that doesn't enter Mrs. Kelly's house in this episode. In fact, he is shown sitting in the Paddy's Pub back office for most of the episode.

Most of these names are the crew of the show. "Load wiper" is possibly a callback to the Season 6 episode "Charlie Kelly: King of the Rats", when Charlie and Frank met a janitor at a spa who told them "I'm the guy who wipes down the loads."
