Oops!

It's happened to us all. 

The embarrassing typo.

 
Here's one of mine:
 
The word was supposed to be "shift"
 
I wrote (and submitted) the word without the "f".
 
The line was supposed to read: "A subtle shift can have a major impact."
 
I didn't catch it.
 
The designer didn't catch it.
 
The client did.
 
Before it went public, thank goodness.
 
Everybody had a good laugh, but I was mortified.
