You Guys Believe Me...Right?

Ever have a friend that seemingly knows more about any given subject than you do, or at least claims to?  The subtle note of bullshit just lingering below the surface.  Any challenge to this claims will only compound the bullshit, it's humorous to see to what extent it will go.  Each boast or claim is bound to vary in it's feasibility.  I would make a chart or an equation to represent this claim, but that would take entirely too much time and effort.  What we do like to do in the presence of the friend in question is assign a numerical value to the level of bullshit that it is between 1-10.  While it would be perfectly acceptable to wait until the bullshitter is unaware, and hold up the appropriate number of fingers, try this instead: speak the number aloud, or find a clever way to work it into conversation.

This is a game that everyone is in on with the exception of the bullshitter.  My friends and I have conduct this game unbeknown-st to the person against whom we play.  Amazingly enough, he has never caught on to the peculiarity or the abruptness that he is cut off in conversation by numbers.  He'll be on a bullshit rant, when someone will suddenly - "Ten!" in his face.

"Ten what?"
Time to deftly change the subject "Ten minutes until we have to be (insert place)"

Everyone knows that guy.  So let the game begin
