Mamie just love the envelope thing! 
So, let's run it up the flagpole and see if anyone salutes, or let me throw this in your goldfish bowl and see if it blows bubbles.
A couple that I always hated, even though I will grudgingly admit that they have a grain of truth:
There is no "I" in team (please pass the sick bowl, I'll try not to miss and puke all over your silly new mens fashion pointy shoes that no-ones toes could possibly go to the end of)
Don't assume, it only makes an ass of U and me (sorry, I have already puked up once, would you mind awfully if I just pissed myself laughing at your hackneyed phrase this time?)
