Quagmire: Oh God.
Joe: I uh I never picked up an illegal alien at Home Depot to take home a choke me while I touch myself.
Quagmire: Oh come on!
Peter: I never did the same thing except with someone from Joann Fabrics.
Quagmire: Oh God this is ridiculous. You guys suck! (Drinks more and passes out.)
Hotel Manager: And this is the bathroom, but watch out we got some bad roaches here.
Red Roach: Hey, you're on our turf man!

Mr. Pewterschmidt: Are you calling me gay?
Peter: No. No. I just; I just thought you might want some extra seamen on your poopdeck.
Peter: (narrating his own life) "I walked into the kitchen and sat down at the table. I looked with a grimace at the questionable meal Lois had placed in front of me. Of course I'd never tell her how disgusted I was with her cooking, but somehow I think she knew. Lois had always been full of energy and life, but lately I had begun to grow more aware of her aging. The bright, exuberant eyes that I had fallen in love with were now beginning to grow dull and listless with the long fatigue of a weary life. (Lois knocks Peter out.)
I woke several hours later in a daze."
And last, but not least, of course the infamous:
Stewie: How you uh, how you comin' on that novel you're working on? Huh? Gotta a big, uh, big stack of papers there? Gotta, gotta nice litte story you're working on there? Your big novel you've been working on for 3 years? Huh? Gotta, gotta compelling protaganist? Yeah? Gotta obstacle for him to overcome? Huh? Gotta story brewing there? Working on, working on that for quite some time? Huh? (voice getting higher pitched) Yea, talking about that 3 years ago. Been working on that the whole time? Nice little narrative? Beginning, middle, and end? Some friends become enemies, some enemies become friends? At the end your main character is richer from the experience? Yeah? Yeah? (voice returns to normal) No, no, you deserve some time off.
