Who is the Master?

Q:  Even CNN calls the choice of General McMaster as Trump's national security adviser "brilliant."  Got me thinking how many good things have "master" in them.  What/who are your top three?

DoA:  My dad would definitely say The Masters.  I'm going Masters of the Universe,  Mary Stuart Masterson, and this clip (which, unfortunately, contains some bad language).

What's your favorite master?  And is there anything bad with master in it?
