Mission Impossible

Have you ever noticed that on Mission Impossible (The TV show & the movie too) that no matter what, the mission is resolved successfully..? Always.

Shouldn't they call it Mission Probable or even Mission Highly Probable???

How about Mission Almost 100% Fucking Certain?
Getting a boner is out. It's seen as too boorish and manly in this new age of sensitive guy television like Ed and West Wing.
