Question: In the alternate timeline, Quagmire and Lois are married. In the kitchen, Lois takes a pie out of the oven and Quagmire says "Hey honey I'm ready for your pie and you made dessert too". Now I know this is some sort of sex joke or dirty pun. But what exactly does the joke mean?
Chosen answer: Pie is a slang for a woman's vagina. That's the meaning of this double entendre. He want to have sex with her and she just happened to have baked dessert.
Answer: It's called "Mr. Night" by Kenny Loggins. It's a reference to Caddyshack, when Cindy Morgan walks by the caddies next to the pool.
