How do you fire a guy?

I'm serious. How does this go down? I'm not in a job where I've ever had to fire someone nor have I ever been fired. How does the conversation go when they both know what's coming? Are there attorneys present? Is RR "escorted from his office" by security? Are all of his U of M privileges revoked? Is he given a severance check on the spot? Fill me in MGoExecutives.
