5. Matt Groening Signature On The Side Of Homers Head
Not so much an Easter egg but more a well known fact nowadays is the fact that the hair above Homers ear and his ear make the shape of MG, which of course stands for Matt Groening. However apparently Mr Groening has decided to tone this down a little in recent years by making the ear less like a G as he believed once the secret had got out it may have become distracting for audiences who were now aware of the fact. Needless to say however it is very noticeable in the first few seasons especially.
