If you can hang on to your career long enough, one of the rewards of entering the venerable senior category in the world of show business is that you can get away with a lot.

All of which Regis takes full of advantage of on Robert Downey Jr.'s time.
That's right, Reeg, beards are hot right now. It is, after all, the late nineteenth century.
