This sounds like it would be tacky, but it's surprisingly touching:

Nice that it was a spontaneous idea by his family.Seb, 26, who bore an amazing resemblance to Dr Who actor David Tennant, died from head injuries after a fall at a friend’s barbecue.
His parents knew he would not want sombre music or a religious ceremony, so they arranged a funeral that celebrated his love of the show.
So the 200 mourners who arrived at the crematorium yesterday were handed a service card with a picture of Seb dressed as Tennant and holding the Doctor’s sonic screwdriver
Emblazoned across the glossy card were the words: “I’m a Time Lord – I’m not a human being. I walk in eternity.”




Come on man. Even then regular autopsies do involve removing internal organs from the body cavity. Either way, you'll still be injected with chemicals and sewn up in various orifices when you die, so what does it matter? You're dead.
