Alfred Chicken Trivia (NES)
Alfred Chicken PartyMindscape came up with a unique promotional ploy for this game - they got a guy to go round dressed in a chicken suit, and entered him into the European Parliament Elections under the 'Alfred Chicken' party banner. This earned lots of attention outside the specialist press (at a time when videogames were being blamed for every societal problem), but surprisingly he didn't win the seat.
Promotional NumberAnother (much less elaborate) promotional gimmick used by Mindscape for this game was a toll-free number you could call (1-800-ALFREDC) that would play a recorded message from Alfred himself.
