I am going to watch this fifteen times in a row and laugh my ass off every time.
Also, the best knock knock joke of all time:
Ayn Rand: Knock knock
Rob Delaney: Who’s there?
RD: John who?
AR: John Galt.
RD: I don’t get it.
AR: John Galt!
RD: Just because you said it twice . . .
AR: He would never knock. If he wants to come in, he opens the door. He is a man.
