Why is it that whenever you have a delivery or repair guy give you a window of time they will be at your house, they always arrive at the end of the time window?  So if they saw they will be there between 12-4 they always get there at 4.  This always happens to me.  They never arrive at 12.  So I'm always stuck waiting the entire time.  Even if it's early and you think you might be the first on the list...nope.  End of the window.  It's so weird.  It might just be me, but I doubt it.  I think it happens to everybody. 

I found this video online.  I think it's been around for a while, but I just saw it for the first time.  I was laughing my ass off.  It is a brilliant prank.  Enjoy....
