How to convince people to use revision control

[Weston Cerny]

Write a script that commits code late at night after everyone else had 
checked in.
Have the script move functions/methods around within a file.
Functionally it shouldn't change anything except this person's ability 
to get work done.
Either they update to a nightmare everyday or a nightmare when they 
update before commit.
Remember always be a nice guy and work with others the way they work 
with you.
Fittier, Happier, more productive.
