The Disgruntled Prime Postulate
It has eluded the greatest mathematic minds for millennia. Euclid's filthy-mouthed brother-in-law, Fellatio, first wondered about the Disgruntled Prime. He proved that there existed prime numbers separated by 6^1, such as 7 and 13, but did not make further progress towards the true Disgruntled prime of 6^9. Later, Isaac Newton's estranged uncle, Festivus, prepared an incomplete proof of what was then called the Exasperatum Prima Postulata. He claimed to have discovered two prime numbers separated by 6^9, but his documents only show the values of 241 and 1679857, which are separated by 6^8.
It wasn't until the early 21st century that persistence and serendipity collided to produce what is thought to be the first conclusive proof of the Disgruntled Prime Postulate. A formal proof was prepared by Vorpus, Gati and Sanji while hovered near a dying fire in a smoky tavern in Palatine, IL, USA. However it was lost during a surprisingly robust performance in the Feats of Strength.
