S11E12: Valentine's Day in Quahog
Hey, Stewie, what are you doing?
Well, Brian, in honor of Valentine's Day,
I thought, "Why not go back in time "to that Summer of Love in the '60s "that everyone's always talking about?"
Hey, you think you might be able to get me some acid?
I'll get you a rolled-up newspaper on the snout is what I'll get you.
Very bad dog.
