yeah i've done that a couple times, where people didn't know what was going on. also one time in a web design class this kid was watching Tim Durtchi's edias segment.
when the dub on pyramid happened i was like:
me: so dope, pyramids huge
him: wtf are you talking about
me: the gap he threw a dub flat over
him: seriously wtf are you talking about.
me: its a trick. are you going to the grand bizarre premier
him: wtf are you talking about
me: its a movie, made by the same people who made that
him: they make movies??
me: yeah
then he kind of just looked at me weird
