Occasionally I walk up to a friend, looking all concerned, then say "Hey man, you got a minute?"
And when they say yeah, what's up, I go "WOULD YOU LIKE TO HEAR ABOUT OUR PERSONAL LORD AND SAVIOUR JESUS CHRIST?"
The looks of "Oh shit, I shouldn't have said yeah" on their face is priceless, especially if they don't know you that well, and think you're serious.
