Michael & Jack: "Grandpa, can you tuck us in? Why are you the best tucker-inner?"
Grandpa: "Because I used to tuck your Dad in and I am really good at tucking little boys in."
Grandpa tucks them both in gently
Jack: "What's so good about that?!" (obviously upset about Grandpa's inferior tucking-in skills)Michael: "That was really good, Grandpa! Thank you!"
