Birthday

Birthdays in the 31st century are much like the birthdays celebrated 1000 years ago. The words to the birthday song have changed, and the tune is similar but legally distinct.

Birthday Cake
Of course a cake is traditional to have at a Birthday. Some characters like Nibbler and Amy have large cakes whilst others like Dr. Zoidberg get only a small cupcake.

The Birthday Song

It's _____'s birthday,
