How the hosts use it
Used as a greeting or shout-out to Jack Quaid, often as 'hey Quaid, what are you cooking?'. Also a mock-title for the only known double Quaid, tied to the Quaid Army and the reply 'righteous kill'.
Why fans love it
The sketch name Quado, the Total Recall character Quato/Kuato, and a real actor named Quaid collide. Jack hears his own name from his speakers and the hosts imagine him in a frat-house apartment making mac and cheese and split hot dogs. The Quaid Army and the call-and-response keep the bit growing.
