The verbal tic of dunderheads, morons and wannabe Californians (read: Seattle denizens and their ilk.) It is not intended as an actual question but rather is the reactionary knee-jerk of someone who does not think before opening the mouth.
Me: I just got this latte for uber cheap at the Starbucks on the corner.

Me: No, I'm just pulling your motherfucking leg. Of COURSE I'm serious!

The Phrase: *You Serious Clark?* is appropriately used when someone around you says something so outrageous that you cannot believe they actually just said that.

This phrase was taken from the movie *National Lampoon's: Christmas Vacation*.

Sitting at the table for Christmas dinner, Clark Griswold mentions that he heard a pilot flying over New York spotted Santa Claus, to excite the children about Christmas, but Cousin Eddie found it necessary to respond with *You Serious Clark?*
