Headache

A picture of the headache phenomenon.

A headache is a rare phenomenon that is experienced after spending too much time shouting "I AM THE EGGMAN!". However, strangely enough, when scientists tested if it would occur when shouting "THEY ARE THE EGGMEN!", "I AM THE WALRUS!" or "KOO KOO KA CHOO KOO KOO KA CHOO", it did not have the same effects. Instead, after shouting these phrases for one hour, their brains turned to lima beans and their legs turned to chicken. It is still unknown how this happened to the scientists.
