Office Rat-A-Tat: when typos get in the way

I thought we'd take a break from the most dangerous and worst-paying type job posts and delve into something that has followed me around my office career like the boogieman on an unlit street in the dark of winter (okay, a little poetic hyperbole folks, but still"¦): the dreaded typo.
I can't tell you how many times I've proofed and re-proofed memos, letters and emails to my higher-ups trying to smoke out a there for a their, or a your for a you're, a where for a wear, a four for, um, a for.

Interestingly, have you ever noticed how communiqués from superiors, on the other hand, especially presidents and senior vice-presidents, show no sign of proofing? Like typos don't matter when the memo is being sent down from above? What's with that? Why the double-standards? They expect you to be on your typing game, but they're free to type with their feet if they want.

Anyone want to comment about that funny (not) fact?

In other typo news, did anyone catch the humorous NASA misprint a couple months ago when the shuttle Endeavour (named after HM Bark Endeavour, the ship commanded by 18th century explorer James Cook, if you're wondering why the British spelling) was rolled out with a banner that read "Go Endeavor!"? Okay, an easy typo because it's not the way we are used to spelling the word. NASA's sign-dept. quickly ran out with a reprinted version, as you see in the photos.

Here's a photo I took with my cell phone today at this yummy Indian joint up on Melrose. Looks like someone needs to buy a vowel, twice! What's the funniest typo you've ever scene?[BTW: how many typos can you find in this post? There are several, if you was paying attention.]
