They moved the holiday to a Monday so it's a three-day holiday. 
	Then they want to leave on Friday to take full advantage of it.
	But everyone's leaving on Friday, and everyone wants to beat the
	traffic, so they leave on Thursday.  And if you're leaving on
	Thursday, why not Wednesday night?  And you can't come back on
	Monday -- that's still a holiday.  And you can't come back on
	Tuesday 'cause everybody comes back on Tuesday, so you outsmart
	everybody and you come back on Wednesday. So now you're leaving
	on Wednesday and coming back on Wednesday, and suddenly a
	one-day holiday is now a week!
