The American Academy of Neurology issued a statement this week urging professional athletes with suspected concussions to wait until they are deceased before sending in their brains for research. 'We already have numerous brains to study, so please stop prying open your skulls with chisels and crowbars and scooping your brain matter into a mailing envelopes,' said AAN president Bruce Sigsbee MD, adding that neurologists have also received the decapitated heads of 200 professional athletes who could not figure out how to remove their brains from their skulls. 'However, if athletes do feel compelled to ship us their brains before their death, we recommend they not bash in their heads with a large rock to retrieve it, as it may damage the neural tissue and prevent proper diagnosis.' Sources at the U.S. postal service confirmed that they have already discovered over 200 professional athletes with their heads stuck in mailboxes after attempting to mail themselves.
