My last boss, the troll, was without question the worst boss, and worst by a huge margin, I have ever had. He was ignorant, functionally illiterate, greedy, self centered, a closet racist and the most extreme misogynist I have ever personally met. He is controlling to the most minuet detail and has no filters - he says things I have never heard anyone say, at least anyone not wearing a sheet or an arm band.
He makes his younger brother Ebenezer look like a reckless spendthrift. He never gives anyone anything. Not a card, a present, even a happy birthday, a happy new year or a Merry Christmas and that includes his kids. He never bought any of them a present and if they got a present it was because his wife of the moment (he's on #5 currently) bought them something and then he raises a big stink for months over it.
He looks kind of like a bowling ball with stubby little arms and legs poking out around the circumference at regular intervals with a cue ball balanced on top with a Yosemite Sam mustache. The mustache was last trimmed about the time Nixon was president and usually showcased bits of the last couple meals he had. He presents as if he lives under a bridge in a cardboard box. He does have a good sense of hygiene though - he bathes once a week most times and you can always tell because that's when he changes his clothes.
