This episode marks the first appearance of Leslie Winkle.
Ignoring the fact that the sword itself doesn't exist, in the beginning of the episode, Sheldon abandons his friends to sell the "sword of Azeroth" on eBay. This is actually possible and normal (for geeks) to do and it's also legal to sell such game items.
The title ("The Fuzzy Boots Corollary") refers to one of the names Leonard would use for some cats in San Diego he heard about. He says he can't decide between "Einstein", "Newton" and "Sergeant Fuzzy Boots".
This episode reveals that Sheldon has asthma.
Series star Johnny Galecki and guest star Sara Gilbert had previously co-starred together on Roseanne playing boyfriend and girlfriend on that show.
Sheldon: At least now you can retrieve the black box from the smoldering wreckage that was once your fantasy of dating her and analyze the data so that you don't crash into geek mountain again.
Howard: So how did it go with Leslie?
Leonard: Oh, we tried kissing, but the Earth didn't move. I mean, any more than the 383 miles that it was gonna move anyway.
Sheldon: You have as much of a chance of having a sexual relationship with Penny as the Hubble telescope does of discovering at the center of a black hole is a little man with a flashlight searching for a circuit breaker.
(Leonard is fretting about his upcoming date with Penny)
Leonard: Oh, you know what? Maybe this isn't such a good idea.
Sheldon: Oh, no, well, now, there's always the possibility that alcohol and poor judgment on her part might lead to a nice romantic evening.
Leonard: I'm having a panic attack.
Sheldon: (stressing over not knowing what to do) Oh, okay. Well, then, calm down!
At the beginning of the episode, Sheldon sells "the Sword of Azeroth" on eBay. However, after only 4 seconds, he claims someone (later revealed Howard) just clicked "Buy It Now". This isn't possible on eBay, however, as items get listed in their database about an hour after it's added. Another problem is that there is NO WAY that any person is able to find the specific entry, go through all the procedures of purchasing and waiting for the transaction to be completed within the 4 seconds until Sheldon says the button's been clicked.
Visual: The guys are playing a multiplayer online game working as a team, though they are on their own individual computers.
The game the guys are playing have several references to "World of Warcraft", which is a multiplayer online role-playing game made by Blizzard Entertainment. However, Howard specifically says "The Sword of Azeroth". "Azeroth" are three different continents in the game, but there is no such thing as a "sword of Azeroth" existing in the game.
Sheldon: Wanna log on to Second Life and go swimming?
"Second Life" (often abbreviated "SL") is a virtual world created by Linden Lab, and was released on June 23, 2003. In the game, you first create an avatar for yourself and then you go exploring the virtual world, which is in many ways just like real life. "Residents" (the name for users) can do anything you can do in real life, like participate in activities, create and trade virtual properties and services with other residents and, just as in Sheldon's example, go swimming.
Sheldon: (...) as the Hubble telescope does of discovering...
The Hubble Space Telescope (often abbreviated "HST") is a telescope in space that was carried into orbit by the space shuttle in April 1990. The Hubble is not the first space telescope, but it is the largest and most versatile one, and it is named after Edwin Hubble, an American astronomer.
Leonard (Johnny Galecki) and Leslie (Sara Gilbert)
The actors playing Leonard (Johnny Galecki) and Leslie (Sara Gilbert) have an acting history together, in which they both starred in the 1988-1997 TV show "Roseanne", that was broadcast on ABC and got the highest ratings on TV during its airing.
Visual: The guys, except for Leonard, are playing Jenga.
Jenga is a game of physical and mental skills created by Leslie Scott and marketed by Milton Bradley Company (a division of Hasbro), in which the rules are that contestants take turns to remove a block from a tower and balance it on top, creating a higher and increasingly unstable structure as the game proceeds.
