Father: Hey, I'm on my way home. You need anything from the store?
Mother: No, I'm good. But I have to warn you...
Father: What?!
Mother: Alex is going to ask you to let him go to a concert in Miami with his friends this weekend.
Father: I see. And how exactly does he plan to get there?
Mother: Well, he intends to borrow your car.
Father: Does he now!
Mother: So I take it that's a no?
Father: Absolutely. He's not insured for my car, number one, and number two, there's a pandemic! Who goes to a concert?!
Kevin: Ronnie says he can beat anyone in this office at tennis.
Danny: Oh can he now! Does he realize that I'm a semi-professional tennis player?
Kevin: Yep, he still says you're no match for him.
Danny: Does he! I almost don't want to play him; it'd be like shooting fish in a barrel.
Kevin: Who knows? Maybe he has hidden talents.
Danny: Hidden talents? He's about 75 pounds overweight! He can barely make it up the stairs in the morning. Oh well, it's his funeral!
