Family Guy, Season 12

Peter and Chris:
Unga-Bunga! Unga-Bunga! Unga-Bunga!

Stewie:
What is that? What's happening?

Peter and Chris:
[carrying mattresses] Unga-Bunga! Unga-Bunga! Unga-Bunga!

Brian:
Peter, what are you doing?

Peter:
Playing "Unga-Bunga". It's the championship.

Stewie:
Go away! This is why Zillow estimates our house at $4.00.

Brian:
What the hell is "Unga-Bunga"?

Peter:
Two guys run into each other with mattresses and, um, that's kinda it.

Chris:
Stop explaining it to the dog! Let's do this!

[Chris and Peter run into each other with mattresses]

Stewie:
Stop it! I'm trying to watch my program!

Peter:
Whoa, Chris, look! Mom's naked!

Chris:
Where?

Peter:
[whacks Chris with his mattress] You creep.

[Chris crashes into the TV and breaks it, much to Stewie's dismay and horror]

Stewie:
[gasp] No!

Lois:
Peter, what's going on in...

Peter:
[whacks Lois with his mattress] Unga-Bunga!

Stewie:
You... You imbeciles! You've ruined my night! I asked for one thing in this house!

Brian:
Stewie, just watch your show upstairs.

Stewie:
I don't want to watch it upstairs on the small TV, I want to watch it downstairs on the big TV! [his face turns red with anger as he starts crying] I WANNA WATCH MY SHOW! [cries, throws himself on the ground and starts throwing his tantrum]

Lois:
Oh no, Stewie's havin' a tantrum. Come here, sweetie. [Stewie bites her thumb] OW! Screw you, ya little turd!

[Stewie throws a photo right at the door and it crashes]

Meg:
[enters the living room] What's all that noise? [sees Stewie upset] Aw, do you want a hug from your big sister? [picks Stewie up and is headbutted] OW!
