This episode has never been aired, nor does it appear in the Season 1 DVD set.
goof: During the Sam and Carla discussion when Derek is in the other room with all the patrons, the positioning of the beer bottles on the tray on the bar changes between shots.
Diane says her father has been dead for 10 years, yet in "Coach's Daughter" she refers to him in the present tense.
In this episode Norm asks Coach if this is the first wedding in Cheers. This would suggest that Coach's knowledge of Cheers dates back before Norm's. Yet in another episode Coach asks Norm who Gus is and Norm says he was two owners ago, which would suggest the opposite.
In the pre-credits teaser Coach and George can be seen playing cards at the bar. This is one of the few times the teaser was not stand-alone and contained elements of the episode's plot.
The age difference between Sam and Diane is cited as six or seven years, or maybe eight or nine. If they wanted to know, it's curious they don't exchange ages. Their real life age difference is less than two years.
It was already established in the episode "The Boys in the Bar" that Cheers had a back door. That's how he got in when he swindled them with the pool table.
The rear entrance has been mentioned in many episodes - remember when Norm used it twice: 1) when he was working as a dishwasher for Melville's, 2) when he was living in Sam's office when everyone thought he was in Bora Bora.
He's Harry "the Hat" notrorious for being a con man/magician, he doesn't need a rear entrance to Cheers to show up in the back room after leaving through the front door. That's the point of the gag!
Near the end of the episode, Harry goes out the front door, supposedly after swindling them all of their money. A few moments later, he reappears from the back room - but there is no rear entrance to Cheers.
There is no back door, but Harry could have slipped in one of the two street level windows that are featured in the poolroom
Nitpick: When Diane returns from the bathroom after fixing her hair, it has been transformed from a frizzy, disheveled mess from riding a motorocycle, to a perfectly coifed, straight 'do. Her make-up has also been redone. Since she was only gone about 30 seconds, it seems highly unlikely that she would have had time to get her hair and make-up so completely perfect in such little time.
Sam was called up in 1973, as he asks Coach later if he remembers the game against Baltimore - all Coach remembers is "it was hot." The Red Sox have several minor league teams in various leagues in the New England/upper New York area, and SAm was with one of these & thus attended Woodstock near the time of the game. Also if he was aa starter he wouldn't have been needed when he didn't pitch.
Sam may have been pitching in the minor leagues - he was drafted from high school, and very, very few major leaguers made the jump from high school to the majors with no minor league experience. (Mike Morgan is one of them.)
Diane answers the phone and tells Sam his date has just cancelled. This in turn makes Sam look through his little black book for a new date for the evening. Sam quickly finds a name and calls her, he says that he met this girl at Woodstock. Woodstock was on the weekend of Aug. 15-18, 1969. Wouldn't Sammy have been pitching for the Red Sox on that weekend? [The Red Sox were in Kansas City 8/15-17 and in Minnesota 8/18-20. The 8/15 game was rained out.]
After Diane turns off the TV and makes her speech then turns it back on again, you can hear it in the background but you can clearly see that the TV is not on when she walks around the bar. You can see it again after Norm comforts her and runs back to watch the game.
The character Ellis Finch, who offers to buy the bar in this episode, was named for the then real-name of the Cheers bar - The Bull & Finch.
Continuity: Norm tells Buzz that he served in the army at Fort Dix, NJ. This is later contradicted in Daddy's Little Middle-Aged Girl, when he tells Rebecca's father that he served in the Coast Guard.
This is the first time that we get to see the men's bathroom in Cheers.
Actually Diane had no reason to ask when Carla and Sam met for she had no idea how old Gino was.
