Lainey: Oh, wow. That's for a baby, which is weird 'cause we were very clear that's a long, long way off.
Beverly: But we blink, and then baby's here, and then there I am, right next to you on my mom cot.
Lainey: Mom cot?
Murray: Oh, no, not the mom cot.
Barry: What does he know? What's a mom cot?
Beverly: It is a cot that sits smack against your bed so when you get tired, you just hand the baby directly to me.
Lainey: Wait. You actually expect to sleep in the same room with us?
Beverly: Trust me, you'll be thrilled to have a bed bubby when it comes time for burping, bathing, and poopy diapies.
Barry: No way, Mother. You are never to set foot in our hypothetical home!
Beverly: I have a copy of the key, right, Murray?
Murray: She made a secret copy.
