Apparently, Hayley has a good singing voice.

Steve and Hayley make out in this episode.

We find out Stan is a member of the National Gun Association.

Roger is right about one thing, Stan and Steve look nothing alike.

The National Gun Association was also mentioned on the Family Guy episode, "And the Weiner Is..." (both Family Guy and American Dad were created by Seth MacFarlane)

Steve: These people aren't rich. Look at their house. It's a box!

Roger: Did you save me a cookie?
Francine: You bet I did. Last one.
Roger: Oh, cookie, you look so good. Shh, shh, don't speak. I'll go get some milk for your bath.

Francine: Oh, sweetheart, don't be so dramatic. Besides, aren't you having fun cooking with mommy?
Hayley: I'm not "cooking with mommy." Dad handcuffed me to the oven.

Roger: What the... Hey, that was my cookie!
Steve: You snooze, you lose.
Roger: "You snooze, you lose," huh? Hmm, okay. Eat up. (Narrows eyes) Eat... up.

Stan: Before we adjourn, let's recite the NGA Oath. Hold hands. Come on, it's not gay, there's guns in the room.

Stan: See? Guns don't kill people. People kill people. Guns defend people against people with smaller guns.
Hayley: You're such a fascist!
Stan: Peace pusher!
Hayley: Murderer!
Stan: Hermaphrodite!

Francine: The point is, there was a time when you two weren't always fighting.
Hayley: That was before I knew Dad was a gun-toting maniac.
Stan: Beatnik!
Hayley: Warmonger!
Stan: Chupacabra!
Hayley: I'm the Mexican Bigfoot?
Stan: You heard her! She admitted it!

Hayley: NGA Land? A gun park?!
Stan: Yeah, Sugar Mountain closed down years ago. This is basically the same thing, except instead of riding a choo-choo through Fairy Book Land, you'll ride a bullet through a mugger's chest.

Stan: Hey, don't worry about me. I'm still your same old dad. What's that sound? Oh, I'm peeing. Fantastic!

Hayley: But you were paralyzed by a gun.
Stan: No, I was paralyzed by you. Look, I'm not going to point fingers here, because I can't. Because of you.

Francine: Look at you two. Who would've thought guns would bring you so close together?
Stan: I know. If only we could get some guns to the Middle East.

Hayley is handcuffed to the oven at the beginning of the episode, before she reveals it, Francine is on her left side, after she reveals it, Francine is on her right side.

Stan is still dry after Hayley throws her guitar in Slime Lake, even though the two NGA directors standing next to him get soaked.

Hayley's forehead isn't bleeding after she bashes her head against the mirror (when she says, "I hate you! You make me sick!")

Stan: Guns don't kill people, people kill people!

That is an exact line from the movie Romeo Must Die

Stannie Get Your Gun

The episode title is a spoof of the movie Annie Get Your Gun

National Gun Association (NGA)

A spoof of the National Rifle Association (NRA).
