Melon
The melon is a kind of comestible in NetHack.
Effects
It is considered vegan food, and gives 100 nutrition when eaten. Thrown melons will "splat" and be wasted.[1]
Strategy
The melon shares the same color glyph with the corpse of Medusa, which has an outside chance of resulting in YASD if the two are confused.

"What is it, Umbopa, son of a fool?" I shouted in Zulu.
"It is food and water, Macumazahn," and again he waved the
green thing.
Then I saw what he had got. It was a melon. We had hit upon
a patch of wild melons, thousands of them, and dead ripe.
"Melons!" I yelled to Good, who was next me; and in another
second he had his false teeth fixed in one.
I think we ate about six each before we had done, and, poor
fruit as they were, I doubt if I ever thought anything nicer.
