Because "head transplant" is more fun to say. It's a self-deprecating joke to say "I need a head transplant". https://twitter.com/search/realtime?q=%22I%20need%20a%20head%20transplant%22&src=typd https://twitter.com/search/realtime?q=%22I%20need%20a%20head... It probably is incorrect, though, as a head transplant would mean that the head would be assuming the identity of the person carrying the body. While amusing it seems a lot to ask of the person with the head. Edit: even more people say "I need a brain transplant" https://twitter.com/search/realtime?q=%22I%20need%20a%20brain%20transplant%22&src=typd https://twitter.com/search/realtime?q=%22I%20need%20a%20brai...
