S8E13: Go, Stewie, Go!
No, not tonight, Lois.
I just had a fart that hurt my balls,
so I'm kind of out of commission right now.
It's one of those ka-blam farts.
Sounds like you're making up excuses.
All right, fine, we'll have sex.
First, turn off the light, get under the covers up to your neck,
turn away from me and lose seven pounds.
Just get the hell out of here!
