Lighten up, Jack. That's called "tongue in cheek humor". We do a lot of that in my neck of the woods. When it;s about a crooked president, we say, "Where is Lee Harvey Oswald when you really need him?" or "Where is John Wilkes Booth when you really need him?".
Is the use of Osama's name really that politically incorrect or did you just fall out of the wrong side of bed?
Furthermore, I believe Osama is as dead as LHO and JWB and therefore can harm no one.
