You want to play the dozens,
Well, the dozens is a game,
But the way I fucked your mother
Was a God damn shame.

Y'know, I'm glad now your mother rejected all my advances, because at least I know you're not my son. There aren't many who can say that...

I'm going all in... just like I did with your momma last night! Turns out she's a really good Poker player.
<Colin> Am I the only one who doesn't find the "your mom" business funny, by the way?
<Colin> as a parody of poor insults it might have been funny
<Colin> three years ago
<Colin> but you have been doing it for literally years now :P
<Asimir> I've been doing your mom for literally years now
Detective Lowe: You're probably in a hurry to get home to your little lady or whatever you call her, huh? The night time is the right time for love and all that, right?
Detective Renee Montoya: That's what your mother tells me.
Draco: And there's a picture, Weasley! A picture of your parents outside their house — if you can call it a house. Your mother could do with losing a bit of weight, couldn't she?
Harry: (trying to hold Ron back) Get stuffed, Malfoy. Come on, Ron —
Draco: Oh yeah, you were staying with them this summer, weren't you Potter? So tell me, is his mother really that porky or is it just the picture?
Harry: You know your mother, Malfoy? The expression on her face — like she's got dung under her nose? Is she like that all the time or just because you were with her?
Draco: Don't you dare insult my mother, Potter.
Lucky: Your mothers had fleas! Your fathers were foxes!
Dagger: (Starting to get angry) You little-!
Lucky: You were born in spoil-boxes! You taste so bad, the fleas spit you out! Your mothers were tailless! You hear me, mange breeders? Your fathers licked sharpclaw spit!
Archie, the chair was old and rickety.
Old and rickety? You'd say a rotten thing like that about something that I hold dear? Do I ever say rotten things like that about the things that you hold dear? Did I ever call your mother old and rickety? Did I ever bust one of her legs?
But the springs was all loose.
So was your mother's.
And it was covered with beer stains.
So was your mother.
And the stuffin' was all comin' out.
You knew her better than me!
Alex Trebek: This is the sound a doggie makes.
Sean Connery: "Moo".
Alex Trebek: That is incorrect.
Sean Connery: Well that's the sound your mother made last night!
Alex Trebek: Aw, come on now, that was totally unnecessary! We would have accepted "bow wow" or "ruff".
Sean Connery: "Rough", eh? Just the way your mother likes it!
Sean Connery: What's the difference between you and a mallard with a cold?
Alex Trebek: What?
Sean Connery: One's a sick duck, and I forget the rest but your mother's a whore.
Sean Connery: Knock knock.
Alex Trebek: Who's there?
Sean Connery: Me. The guy who slept with your mother last night.
