Devil Donuts is a donut cart run by Terrence.
Homer went into the break room in Springfield Nuclear Power Plant one day and found his colleagues with new donuts with 'crazy' toppings. He wanted to eat the rest, but when he went to the box, it was empty. Homer demanded that his colleague Lenny tell him where the donuts came from. He said that the man who does the sexual harassment seminars brought them in. Homer went to the speaker and demanded he tell him where the donuts came from. His answer did not give Homer the information he needed, so he called the police to report a missing donut cart, and Chief Wiggum, along with his colleague Lou, flew a helicopter over Springfield with Homer on board to spot the Devil Donuts donut cart. They found the cart, but when they approached the cart owner, he said that he only makes one batch of donuts a day. Chief Wiggum then pulled out his gun and ordered for more donuts or he was going to shoot. He then pulled it away, and was escorted off by Lou. Homer then sulked on the curb, before the cart owner said that Homer could try a new donut in testing, a donut made entirely out of cake. Homer scoffed the donut down, and the cart owner introduced himself to Homer, and told him he was Terrence.
Devil Donuts are bigger than regular donuts, and are covered in a variety of unusual topping such as Churro's, gummy worms, and in the case of one is made up up several layers of different donuts.
Terrance only makes one batch a day.
