A farmer goes to the mechanic and says:
“There’s water in the carburetor of my tractor.”
The mechanic looks puzzled and replies:
“Water in the carburetor? That’s impossible. Are you sure?”
The farmer insists:
“Absolutely. There’s definitely water in the carburetor.”
The mechanic shakes his head:
“Alright, let me check it myself. Where’s the tractor?”
The farmer calmly says:
“In the pond.”
