Luke (from the bed): Daddy …
Daddy (entering Luke’s room): Yes, little boy?  What do you need?
Luke: I need a drink … I mean, I need to go potty.
Daddy: Well, which is it?
Luke: What do you mean?
Daddy: Do you need a drink, or do you need to go potty?
Luke: You pick.
[translation – I need to get out of bed for whichever excuse you deem viable!]
