S8E21: Partial Terms of Endearment
You gotta get out of here.
Why do we have to leave, Dad?
'Cause your Daddy's gonna have a three-way with your mother and her friend.
Isn't that nice about Daddy's three-way?
I had a one-way one time.
That was amazing. Sorry I farted in the middle.
All right, go on, beat it, all of you.
Peter, you're not gonna be having a three-way with Lois and her friend.
