Corrected entry: At the wedding, Deacon tells Doug that he also had disposable cameras out at his wedding, and that a guy took a photo of his butt. Doug and Deacon are best friends, so Doug would already know this. Doug would have been at the wedding, although it's never specified when Deacon and Kelly were married. (00:07:10)
Corrected entry: In this episode, Carrie is yelling at Doug about their money troubles when he opens a beer and she says, "Oh great, you are having a very expensive foreign beer". Doug is drinking a Heineken, which is a moderately priced, very common beer.
Correction: As we all know, both Doug and Carrie are overly dramatic, and I am sure she was saying this sarcastically just to prove a point and knew that it was not an expensive beer.
Correction: In season 8 episode 3, Consummate Professional, there is a flashback in which they show Doug meeting Deacon for the first time at IPS. You can see Deacon's wedding ring, so they didn't know each other when Deacon got married.
