* A universe that is mostly fire hydrants.
* A universe that consists of homosexuals.

When the cast of How I Met Your Mother appears before King Stewart, they perform a short scene referencing the Bro Code. However, the section of the Bro Code they mention has nothing to do with the scene (a full-length book version of the Bro Code had been published about 7 months before this episode aired). Barney cites Article 15-b and describes it as "the heart of the Bro Code"; this sub-article doesn't exist, however, as Article 15 is "A bro never dances with his hands above his head."
The closest article relating to what they're talking about in the scene would be Article 101: "If a Bro asks another Bro to keep a secret, he shall take that secret to his grave. This is what makes them Bros, not chicks"

This episode reveals that Kevin Swanson, Joe's son, died in Iraq, explaining his sudden disappearance from the show (also, in the DVD commentary for Peter's Two Dads, the creator Seth MacFarlane said that he was a very boring character). However, this is later retconned in Season 10 by stating that Kevin was MIA (Missing in Action).
When Peter, Joe, and Cleveland arrive at Quagmire's house, there is no wheelchair ramp on Quagmire's front step, yet somehow Joe manages to get into the house without any difficulty.
The Adult Swim version replaces the William Shatner joke at the beginning with a new brief shot of people on the convention floor.
