Will you allow me to play MMQB?

One of my favorite sayings is from the Brett Farve/Mastercard commercials.  Farve at the end says, ‘I Woulda Double Bagged It’.  Most of us remember that one.  Enjoy the commercial for old time’s sake.   

When it comes to ventilation systems, the MMQB in me says ‘I woulda used displacement’.
