The “Dub Quest” you ask?  It is the shortened and more sexy version of what is called the “Double Question”.  You may wonder when you have experienced the phenomenon.  The DQ is usually experienced at the start of any event.  It is most likely used at the beginning as it is the way the emcee tries to establish a relationship with the audience.  It usually goes like this:

MC: (Checks mic by tapping on it)  Good evening everyone!  How are you doing?
Crowd: (Mixed grumbling)
MC: I said, how are you doing?
Crowd: (Again, louder mixed grumbling with a few “goods” and “alrights” and usually one smart alec screaming “SUPER!”)
MC: Okay then.  Thanks for coming to Mark Dean Elementary’s 4th grade production of Pulp Fiction…
