Goof: In this episode, there's a flashback of Barney flying to San Francisco to convince Lily to get back together with Marshall, remarking that he can't keep stealing Marshall's dates forever. However, at the time Barney was stealing Marshall's dates ("The Scorpion and the Toad"), Lily was back in NYC already.
When Robin tries to "communicate" with Lily by attempting to read each others' minds, we see this effort fail completely. However, this isn't the first episode in which such an attempt is made. In the first-season episode Mary the Paralegal, we see the "famous telepathic conversations" between Lily and Marshall, as well as Marshall and Ted.
When Barney is in San Francisco asking Lily to go back home he mentions he can't keep stealing girls from Marshall forever. This ties to a previous episode, "The Scorpion and the Toad", in which Barney supposedly teaches Marshall how to hit on women but ends up stealing all candidates from him. Now we know Barney was doing that on purpose to keep Marshall from going on without Lily.
Barney: There's a store on 8th Avenue that specializes in—how to put this delicately—battery... powered... adult... recreational... fake penises.
Ted: We just don't like your naked girls.
Barney: What!? My girls aren't hot enough. I mean, yeah alright fine, the stripper at Stuart's bachelor party was a 15.
Ted: She was 15!!?
Barney: No. A 15. Like in blackjack.
Ted: (pauses to think) ...As in..not sure whether you'd hit it?
Ted: We love naked girls. They're one of the best things in the world. It goes: naked girls, democracy, the scene in Every Which Way But Loose where the monkey gives the guy the finger.
Robin: Check out what I got Lily for her shower. It's kind of racy, think you can handle it?
Barney: I've been in a ten-way, so yeah.
Marshall: It's my bachelor party—no strippers.
Barney: Awww, he thinks he has a choice.
Stuart: Marriage is like jail, right fellas? Except in jail, you get to have sex.
The German episode title is "Pikante Partys", meaning "Spicy Parties". The French title is "L'enterrement de vie de garçon", and the Italian title is "Addio al celibato", both idiomatically exact translations.

When Barney mentions that if the stripper died he'd be willing to help Marshall bury her in the desert, he's borrowing from the plot of the 1998 film, Very Bad Things.
