Joke Top Titles

I am compliling a list of titles that the guy at the top would use (jokingly)

Top Dog
Guy Upstairs
All Around Great Guy
Biggest and Brightest
Maximus Greatus
Top Banana
Omniscient One
Big Kahuna
Big Fish in a Little Pond
El Captitian

Thank you all you great peoples!

I like the term "bull goose loony" from "One Flew Over the Cuckoo's Nest" by Ken Kesey, a novel about a mental hospital. Then there's (from This Dog'll Really Hunt: An Entertaining Texas Dictionary by Wallace O. Chariton), "lead steer" and "big biscuit in the pan." And there's "alpha wolf" and "lead dog." And, from the cartoon "Rocky and Bullwinkle," "Fearless Leader."

'He/She who must be obeyed', 'Top Man', 'Leader of the Pack', 'The Boss', 'guv'(beloved of UK sit com writers), 'The dogs b*******', 'The King of the Dunghill' - the CEO of a small company with pretentions to be a multinational.

Major domo, Kingpin, 800 pound gorilla.

And a Stephen King phrase, King T*rd of S*#t Mountain.

About 20 years ago, Archbishop Alter of Cincinnati was at St. Peter's in Rome, and was going to say mass at a side altar. He was proceeding with great pomp to his destination when a Swiss Guard, singularly unimpressed, cocked an eyebrow and remarked "Procezione de uno." (I'm not sure of the spelling, but the sense is clear enough. A procession of one.)

Leave us not forget a wonderful movie/military reference, "Top Gun" and I believe that "El Capitan" is spelled as indicated. Good stuff!
