Are you tired of all the awareness reminders of sad things in life? Well then, ALWAYS LOOK ON THE BRIGHT SIDE OF LIFE! Put a Monty Python quote on your status and spread the joy! My quote for today: GET ON WITH IT!
What is "Get on with it from"? I can't recall. I can hear John Cleese saying it in my head, but what the heck is it from?
I think you should put a more famous quote at the end, like "Go on, it's wafer thin" or "We shall say 'Ni!' to you, unless you fetch us a shrubbery" or some of the great quotes PP have mentioned.
But to be honest with you, it is a bit much; frankly if I saw this update I'd think someone needs to take some time off from Facebook to chill.

But, you have the right idea in general, to post something funny and non-awareness-y, I just think the tone is too admonishing. So, what about this for a status:
"Always look on the bright side of life! ♪♫" <-- copy this to get the music note characters. They are also in character map.
Or if you really want to mention awareness:
"Awareness shmawareness. Now, I shall say 'Ni!' to you, unless you fetch me a shrubbery!"
I also agree with Sharnita that this is good:
"ALWAYS LOOK ON THE BRIGHT SIDE OF LIFE! Put a Monty Python quote on your status and spread the joy! My quote for today: GET ON WITH IT!"
