I remember around 2005ish, maybe earlier, there was a company that started selling Duff beer here in Australia with the same font as from the Simpsons and a complete clone of the cartoon can design. Everyone thought it was cool and it became very popular very quickly. People were surprised that The Simpsons name would attach itself to a real life beer given it was a family show and this would be ripe for controversy. It came to light after only a couple of months that The Simpsons brand had nothing to do with it and the company had somehow managed to go through all the steps of bringing this to market and just presumably hoped they wouldn’t get in to trouble. They were very quickly made to stop distributing those beers. Weird situation.
