"Come on, James. You're supposed to say, 'who's there?'" "Um, I think you have the wrong number." "I don't think so." "You sound mighty sure of that. But unfortunately for you, I'm mighty sure that I don't know anyone who would be calling to tell me a knock knock joke at four in the morning." "I could tell you a pun instead. I know lots of those, too." "I'd rather you just hang up." "Wait. This isn't James's phone number. You're not James!" "Wow, you're so smart! It only took you one whole minute of conversation! A Scooby snack for you!"
