AnnaS:

Yours is a terrific site! I entered "Christmas is coming; the goose is getting fat"...and so on. Here's the jive version:

Christmas be comin'! Right on!
De goose be gettin' fat! Right on!
Please, t'put some penny in de old man's hat. Man!
Please, t'put some penny in de old man's hat. Man!
If ya''ve no penny,
A ha' penny gots'ta do. 'S coo', bro.
If ya' gots no ha' penny den God bless ya'! Right on!
If ya' gots no ha' penny den God bless ya'! Right on!

Your site is by far better than A.L.I.C.E. Bot's.
