Like everybody else I heard with great interest the news about the attempted solution of the ABC conjecture by Shinichi Mochizuki. (See, e.g., here, here, here, and here.) I did not think that this has much to with me until I discovered yesterday in my room the following remarkable document from 1999.
If the ABC conjecture is proved Professor Zagier will pay G. Kalai 1000 (one thousand) Isreali Shekels. Professor Zagier received 1 shekel in advance from G. Kalai.

Amazing! I almost forgot about the whole thing, but now all left to say is:
Go Shinichi Go!
