Try This Sometime:

Walk up to an armored car parked along the side of the street, reach through the five inch diameter hole in the side of the driver’s door and , with an enthusiastic, “goochie-goochie-goo!” – tickle his tummy. I do this from time to time and I can’t help but think it makes his day. One time this short black tube emerged – I guess his arm wouldn’t fit – and I think it was his way of saying: “Back at ya, buddy!”
