Tongue in cheek
Johnny: Are you going to be here on Saturday?
me: No I won't be there on Saturday... Wait, 23rd or 30th?
Johnny: 30th.
me: No, I have to be back here to work.
Johnny: Well then you should just quit.
me: If I quit I won't have a job at all!
Johnny: Oh yea, without a job you won't be able to pay rent, and then you'll get evicted and be forced to move back home...
me: Is that your master plan?
