two friends bob and sandra are sitting outside a cafe when a third person approaches them. 

person: hey, could one of you guys spare a few coins? 

bob and sandra look at each other in silence. 

person: what, no coins?
 
sandra: we can trade you something else.

person: what's that?

bob: well, we can give you the world's best knock-knock joke. 

person: alright, sounds like a deal. 

sandra: knock, knock. 

person: who's there? 

bob: a broken pencil. 

person: a broken pencil who?

sandra: never mind, it's pointless. 

all three of them burst into laughter.
