OK, just to have something waiting for you tomorrow. This (they say) really happened in Belgrade:

An old lady runs trying to catch a bus, but it's too late. He asks a nearby guy
- Son, was this a [bus number] three?
- Nope, granny, you crossed the line.

(Took me a couple of seconds to understand it. Hint: basketball.)
