In "One Truck, al Dente", Frank and Carol are in a baby care class, trying to learn how to take care of a baby since they're expecting. Frank had his baby doll underwater for too long, and he gets the water out of it by squeezing it. The water squirts at Carol and the instructor.
Frank: That was wrong, wasn't it? Carol: Frank, you're supposed to save the baby, not juice it! Instructor: Don't be too hard on him. A lot of men are nervous about their first baby. Frank: Actually, it's not my first baby, it's my fourth. Instructor: Oh, any survivors?
Later he tries to learn to the baby heimlich. He "firmly" tab between the doll's shoulders, which causes the head to pop off and drop on another couple's baby tub.
Frank accidentally left the doll on top of the car as they're driving home.
Frank: I want you to know that when you leave the baby with me, it's 100% safe.
"You know, they want you to buy American, and they sell you a pile of junk." *throws the rag on the floor* "Unbelievable!"
"I have already killed three kids today, two more will make no difference."
