1. Futurama References
Naturally Futurama, having also been created by Matt Groening is commonly used for Easter eggs in The Simpsons. Whether it is Fry showing up in a Simpsons Cough gag, posters being on walls or geeky kids wearing Futurama tops the references are always enough to bring a little smile to fans faces. Narrowing this down to one references is extremely difficult so for that reason I will leave it open to you to suggest your favourite Futurama reference. My personal favourite is in the episode Mayored to the Mob in season nine where Uter, the little overweight German exchange student is seen wearing a Futurama t-shirt. Why? Simply because Uter is one of my favourite supporting characters and is always very funny whenever he makes an appearance.
