Mott had terrible stats and his only ability was "Barbering" which wasn't mentioned on any other card or required for any missions. And then in the next expansion, there was an Event called "Barber Pole." The entirety of the text was "Plays on Table." Then there was another card that could give any one character the skill of barbering. The plan was to release one in each expansion, though the initial plan for the set got scrapped. When they finally released the "tying up loose ends set" they added a card called "A little off the top" I think that allowed you to use all the barber cards together for an effect that let you skim cards off your opponent's deck. It was pretty powerful, but really not worth it.
In the meantime, though, people found goofy ways to use the useless cards. Like putting Mott in a shuttlecraft with self destruct and using it as a guided missile.
And Parallax Arguers was this delightfully vague card that let you gain VP "if that was cool."
