Oh and here is the best knock knock EVER!
You: I have a GREAT knock knock joke you won't believe it it is so great.
Other party:Okay you seem a bit worked up over a knock knock joke but...okay let's hear it.
You: Okay but you have to start it off
Other party: Okay..Knock knock
You: Who's there?
Other party:
usually stunned silence follows sometimes mewling noises if they are stoned or drunk but fun confusion nevertheless..go try it on someone immediately.
It made my brain hurt when I was victimized with it
