Q: Why shouldn’t you tell secrets on a farm?
A: Because the potatoes have eyes and the corn has ears!
Explanation: Ah, yes- more food jokes!
When you look at a potato, you will see it has small bumps sticking out. It is from these points that new potato plants will grow. These points are called eyes, potato eyes. No, potatoes cannot see with their eyes.
An ear of corn was explained here. When you take corn from the field, harvest the corn, you are taking the ears off of the plant.
This joke is funny because it plays with the word eyes (eyes you see with/eyes of a potato) and ears (ears you hear with/ears of corn). If potatoes can see you and the corn can hear you, you probably shouldn’t tell secrets!
