The Future Checkbook

Nobita wants money to buy the new comic book series his friends had bought, but Mom won't give him. Doraemon gives him a checkbook so Nobita can buy the comic by writing any amount of money on the check and sign it. Nobita proceeds to buy many things and give Gian and Suneo 1000 yen each with the checkbook, but when Nobita's pocket money Mom and Uncle Nobirou give disappears, Doraemon urges him to return all the stuff to avoid having to wait until he is 43 years old to earn money again.
