any facebook application

i need any facebook application you have in stock. 1. you don't need to create/edit anything. i just need it for sampling. 2. it should involve the use of a MySQL database. 3. it should use FBML extensively (that is, a facebook canvas, NOT iframe) 4. it should be a website application. 5. it should retrieve user's information and user's friend's information. 6. it must be bug-free.
