This episode was not intended to be the last episode of the series. It was on hiatus for about a month and then ended.
Alyssa: Who gave you the last piece of advice?
Willy: You don't wanna know.
Rock: You're as hot as ashphalt.
Rock: I wrote a song. I call it, "Crystal Clear".
Crystal: We are on the same cosmic plane after all.
Rock: Having some trouble in the love department, huh, Willy?
Crystal: Today has been an emotional roller coaster!
Crystal: What in the cosmos are we doing here?!
Willy: Alyssa's smart, funny, pretty. I think I'm going to like her.
Quincy: Go get her, dog!
Serenity: How's the date going with your girlfriend?
Serenity: Wake up and smell the obvious!!
Serenity: Hot date, huh, Romeo?
Quincy: My friendship cannot be bribed by material needs, bro.
Quincy: If I can't go, you guys can't go!
Alyssa: Buzz is right, Willy. There's nothing to talk about.
Willy: Yes there is. Starting with how I feel about you.
Serentiy: (in a Valley Girl accent) H e l l o Rom-ah-o, you just got dumped.
This is the first episode that Rock and Crystal got in an argument.
Willy and Alyssa kissed on the lips in this episode.
Apparently, Alyssa has had feelings for Willy for a long time.
Mosh didn't appear in this episode.
Rock's Song: Crystal Clear
Rock Zilla actually helped Willy in this episode to get together with Alyssa. This makes up for every terrible thing he's done throughout the series.
In this episode, it's the Zillas' (Rock and Crystal) 20th Year Anniversary.
This hints that Rock and Crystal are at least 38 (as 18 is the youngest legal marrying age, 20 + 18 = 38), though it's more likely that they are in their 40s - especially considering how upset Rock was when he learned how long he and Crystal had been married.
Quincy was afraid he'd lose Willy's and Alyssa's friendship.
Buzz liked Alyssa too.
Buzz has the last line in the series.
Quincy: We're like the Three Amigos!
This is a reference to the 1986 comedy film ¡Three Amigos!, starring Steve Martin, Martin Short, and Chevy Chase.
