Katy: "Dada, what do you want for Christmas?"
Me: "Katy, I just want you to be happy. That would be the best present for me"
Katy: "Dada, I don't know if Santa can bring that"
Katy: "Dada, what's your last name?"
Me: "Well, what's your last name?"
Katy: "Goff"
Me: "Then what do you think my last name is?"
Katy: "Still Dada?"
