To a very close approximation, I ate my own body weight in cake over the weekend. Yet when I weigh myself today, I seem to be exactly the same weight as last Friday. Clearly there is but one explanation: I am actually a replica Neil constructed entirely of cake.
Acting on this, I will begin searching for a giant-size Tupperware container to prevent myself going stale.
The worst case scenario is that my original body comes demanding it's old life back, around 4 in the afternoon when it's feeling a bit peckish.
(Incidentally Cakkelganger currently gets no hits on google. I claim it as a new word!)
