Drumstick (Mario's Time Machine)
From the Super Mario Wiki
The Drumstick is an item in the SNES and PC releases of Mario's Time Machine. It is a chicken drumstick that is obtained from a scribe in 1455 Mainz, who casually gives it to Mario while talking about his wife's cooking. Mario then gives it to a nearby metalworker, who is only willing to talk further about Johann Gutenberg if he is given something to eat. After receiving the Drumstick, he then says that he was planning on having a Hamburger and a Frankfurter for lunch, but they failed to appear (the joke being that Hamburg and Frankfurt are places in Germany, whereas hamburgers and frankfurters are both foods).
