This joke is so corny I could eat it off the cob.
What happened when the corn got scolded? He got an earful!
Why couldn't the man get out of the maize maze?
He got corn-ered!
I guess that corn is a-maize-ing.
Why shouldn't you tell a secret in a corn field?
Because they are full of ears!
Now that was a corny joke.
And yes, it was rather a-maize-ing.
Wanna hear a joke about corn?
Never mind, it's too corny.
