John Goodman or Sir Issac Newton. Sur le herbe.
Newton never married, had kids or was ever seen on any date with any woman.
Only close friend was this one younger French mathematician named Fatio.
It was widely accepted that Newton had a nervous break down when Fatio left and returned to Paris.
Most likely a closet case, getbigger.
Having said that, I'd still try for a threesome with chunky John Goodman and Sir Issac, provided he wear that long powder wigs of curls.
