What does it mean?

Hello everyone,

What is the meaning of "see you later alligator"
Is it only goodbye?
Is it funny?
Is there any hidden meaning for such expression?

 

[Shakespeare's brother]

It's part of the endearing phrase: 'see you later alligator'...to which the response would be: 'in a while crocodile'; to my knowledge a harmless goodbye slogan.

Dear, Shakespeare's brother

Thank you very much.
