Warner Bros. artist Kirk Mueller was a frequent customer of the Coffee Shop and actually lived in the Hotel for awhile. He became a personal friend of Michael’s and dated his sister (which is another story for another time). He was as zany as the Looney Tunes characters he so ably drew, especially his alter ego, Bugs Bunny.

The Beetlejuice character created by Michael Keaton that always reminded me of Kirk.
Not to be confused with Sir John Herschel, the astronomer, who first described variations in the brightness of the star Betelgeuse.
