Futurama Easter Egg - 1138

In the episode 'I Second That Emotion', the gang is celebrating Nibbler's birthday. When Bender goes to play 'pin the tail on the moon maggot', he closes his eyes and cheats by using his targeting screen. There is a column of numbers on the left side that change seemingly at random. But when the numbers stop, an 1138 can be seen. The 1st number is 11. The second is 3, and the 3rd number is 8.
