There are several solutions, but all of them are logical statements involving "you will tell me your name" and "you will grant me (3) wishes". In each situation, a contradiction is reached unless the genie grants the wishes.

• "You will not tell me your name nor grant me three wishes."
• "You will not tell me your name, or you will grant me three wishes."

I got the idea from a John Allen Paulos article on abcnews.
