I've been to enough places by now to have heard many times a phrase that goes like this:

"Well we have a little saying 'round these parts: If you don't like the weather, then stick around for another five minutes! Hyuk, hyuk!"
I have startling news for you people: EVERYONE in virtually every part of the country makes this same wacky joke about the region in which they live. It's not unique, so please stop saying it.
In any area where the weather occasionally changes (which is everywhere) this colorful phrase is used. I've even heard people use this line in Fresno for crying out loud, which probably has the most mundane, unchanging weather in the nation.
I will grant that Colorado definitely has some of the most extreme weather ranges that I've ever experienced. Two weeks ago, I was out hiking in short sleeves and it was bright, sunny, and 75 degrees. The very next day it was 20 degrees and snowed heavily all day. In my book, that's quite an impressive meterological spectrum for spanning a mere weekend.
But seriously, don't use that phrase anymore, for I am tired of hearing it. Thank you for your consideration and good evening.
