Birthday

Birthdays in the 31st century are much like the birthdays celebrated 1000 years ago.

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
What day is today?

It's _____'s birthday,

What a day for a birthday,

Let's all have some cake

Appearances

 * (Nibbler)
 * (Leela)

Reason For Different Song And Melody
The cast sings a different birthday song than the one used in our time (different lyrics and melody). Either because in the future this new song is the norm, or because Warner Music Group still owns the copyright to our currently used song.

Appearances

 * - Professor Hubert J. Farnsworth's birthday
