Machine language time code

The Machine language time code or simply the time code is a code appearing in a tattoo on Fry's butt.

The code
The code appearing in the film is as follows; 001100 010010 011110 100001 101101 110011

As you can tell, it is mirrored over the first three columns over to the last three and inverted over the first three rows to the last three. If you remove the last three columns, you can tell that the first three columns are actually just the numbers 1 to 6 in binary.

It's interesting to note that it has yet to be truly explained where the time code comes from or how it ended up on Fry's butt in the first place. (i.e. it was put on the frozen Fry's butt by Bender using a flap of skin from Lars but it only existed on Lars's butt because he is a paradox time copy of Fry.), meaning it is a paradoxical object known as a paradox-origin. Another example of a paradox-origin is if your future self were to travel back in time and give yourself something, it can be deduced that it is a paradox-origin. However, in the original draft of the script, Bender, while waiting for Fry to come back from the future (this being Bender-2, who gets kicked into the freezer tube), watches the lottery and writes down the winning numbers, converts them to binary and mirrors them, then inscribes them on Fry's butt, hiding them from Bender-1 and planning to return and win the lottery (unaware that he is doomed as a time paradox duplicate).
