I'll post three answers to this topic.
A Scientifically correct answer: A cake which is a material object, cannot lie and it also cannot tell the truth, and there are over 18 million cakes standing around in exsitance right now, probably there are more cakes made in history than people.
A noob answer: ORLY?
A "Sprint" Answer: The cake is a lie, because you cannot successfully reproduce a cake inside of a video game, although if you create a cake, you may prove it is not a lie, but there are too many fat asses in this country, and it will be gone before Hell freezes over anyways.
