Well...

One of Ryan's friends asked Danny a funny question yesterday...
Friend:  So technically, are you a real cop?
Danny:  Well, if I put my handcuffs on you and took you to jail, would you think I was a real cop?

Ryan informs us there is more to the story, and it stems from a game of "Apples to Apples" they played the other night.  I think it is much funnier without the back story.
