Harold occasionally mentions watching Traders, a show where Patrick McKenna played the role of Marty.
One of Edgar K.B. Montrose's first appearances had him talking about the film Dances with Wolves, talking about how the "Native guy" (the role played by actor Graham Greene) should have gotten the Oscar.
Wayne Robson played a down-and-out man in One Magic Christmas, who is so desperate for some money that he robs a bank — and accidentally commits murder! Not to mention hijacks a car with some kids in it!
Hap Shaughnessy always wears a cap bearing the crest of the Royal Canadian Regiment. Gordon Pinsent served for four years in that unit.
Cast the Expert: Joel Harris (who played Young Walter) is a professional stuntman, making him all the more qualified to portray one of Possum Lake's resident butt monkeys.
Dawson Casting: An egregious example; McKenna was 31 when he started playing teen-aged Harold. Averted in the later episodes, in which Harold was portrayed as an adult.
Doing It for the Art: The 4th-6th seasons. As Steve Smith mentioned on the DVD sets, the company had to buy time slots in order for the show to air (this is also why the show was titled "The New Red Green Show" during this time, to differentiate it from seasons 1-3 that were still airing in reruns). Luckily, by season 7 they had secured a deal with CBC, so they didn't have to pay to air their own show anymore.
This is also why Steve Smith decided to end the show at the 15th season: He didn't want to start letting down loyal viewers by delivering a sub-standard product.
Executive Meddling: Steve Smith isn't too fond of the second season, during which the executives pressed him to make the show into more of a sitcom. Hence the expanded cast and plotlines that we actually saw develop, as opposed to simply being related by Red. When Smith got back full creative control from the third season onwards, he went back to the old format. That said, one major aspect of the show did originate in the second season and was kept thereafter: The possum squeal sound effect which signaled the start of the lodge meeting.
Written by Cast Member: Taken to its literal conclusion. Steve Smith co-wrote all 300 episodes. Rick Green co-wrote every episode for the first eight seasons and the last two or three seasons. Other cast members like Peter Wildman (Buzz), Bob Bainborough (Dalton), Jeff Lumby (Winston) and even Patrick McKenna would also contribute to dozens of episodes in their own right.
Adventures With Bill: Black-and-white segment featuring tons of slapstick as Bill tries to do something for fun but fails spectacularly. Red narrates the proceedings. Eventually, other characters joined the fun. During seasons 9-12, Bill was replaced by Walter, a younger guy (and, in real life, stunt coordinator for the series). Walter would stick around when Bill returned to the show, however.
Auto Biography: Only seen during season 6. A Possum Lodge member waxes about their favorite vehicle.
Buddy System: Debuted during season 4. Red and another character address the camera about a problem they just created (usually something stupid the unseen character said to his wife).
The Experts: Harold reads a letter from a viewer, asking their advice on a topic. It's always answered by Red and another character.
Famous People In Possum Lake History: Debuted during season 9. Red would present a biography of an interesting person of Possum Lake, and other characters would add their two cents.
Fishing Conversations: Debuted during season 11. Red and two other characters (usually Mike and Dalton) would talk about various topics while fishing. The topics tended to be serious, but jokes were peppered in anyway. This segment is notable because it doesn't contain audience laughter or a laugh track, at least not until the last joke.
Handyman Corner: Red uses various scraps to create inventions, (almost) always ending each segment with a Catch Phrase: "If the women don't find you handsome, they should at least find you handy." While this segment used to be limited to Once an Episode, around the 9th season there were multiple Handyman Corners throughout an episode: A short one featured as a Cold Open, then the main one during the first segment, and another short one during the third segment.
Harold at the Office: Only aired during season 9. Red would visit Harold at his office in the big city, where Harold would usually be exceptionally busy and Red would embarrass him.
Harold's Handy Crafts: Debuted during season 5. A Harold version of "Handyman Corner".
Harold's Hobby House: Debuted during season 14. Harold and another character talk about some crafts they made. This segment is notable among Whose Line Is It Anyway? fans for having a special guest appearance by Colin Mochrie as Frank Kepke, a sausage and wiener sculptor.
Harold's Segments: Debuted during season 3. Harold addressed the teenagers in the audience about various topics. Often ended with Red crashing the sketch and making a snarky comment.
If It Ain't Broke, You're Not Trying: Debuted during season 7. Ostensibly a fix-it segment, the emphasis is more on explaining how the item in question was broken in the first place, such as Dalton's wife hitting him over the head with a tennis racket.
Male Call: Letters from viewers.
Men Anonymous: Debuted during season 6. A parody of "Alcoholics Anonymous", except with the men declaring that they resisted acting like a stereotypical man for a certain amount of time.
Mike's Teen Talk: Debuted during season 9. Identical to "Red's Advice to Teenagers", but with Mike instead of Red.
New Member Night: Debuted during season 8. Red invites lodge members to introduce prospective new members, all of whom have some special quirk that the introducing member finds appealing, and then Red has the lodge members vote whether to let him. The introducing member usually convinces everyone to vote yes by giving them an incentive for doing so.
In a commentary by Steve Smith on a Red Green DVD, the prospective new members are actually played by someone from the studio audience that the actors on the show would randomly pick to stand up there in front of everyone and make jokes about.
North of Forty / Red's Sage Advice: Debuted during season 4. Red, sitting at his desk, gives humorous advice, usually to middle-aged married men.
Poetry / Winter of Our Discount Tent: Red reads a poem or passage from a book. During seasons 1-3, the poems often took on a theme based on a season (e.g. "It is winter/It is spring").
Possum 911: Debuted during season 6. A character calls in to Possum 911 about a problem, usually trivial.
Possum Lodge Word Game: Debuted during season 5. One member has to get another to guess a word, but always has difficulty doing so. The word is frequently guessed by accident.
Ranger Gord's Educational Films: Debuted during season 9. A series of animated cartoons done by Ranger Gord (in real life, animated by Bryce Hallett). Gord was portrayed as a handsome, buff stud, while Red and Harold were portrayed as beavers. Ironically, it was Red and Harold who gave the correct advice, while Gord was always wrong.
Red's Advice to Teenagers: Similar to "Red's Sage Advice", except it addresses teens and usually takes place outdoors.
Red's Campfire Songs: Red plays guitar while singing a song with a punchline. Harold accompanies on "percussion". This segment was absent from seasons 9-13 before making a brief return appearance in season 14's Christmas special.
Talking Animals: Debuted during season 8. Animal expert Ed Frid fearfully introduces the day's animal.
