Answer:
A potato is a vegetable until it becomes a couch!
Step-by-step explanation:
This statement is a nonsensical play on words and does not have a scientific explanation. It is a humorous statement that creates an unexpected and absurd image in the listener's mind, as a potato and a couch are two completely unrelated things. The statement relies on the ambiguity of the word "becomes," which can be interpreted in many ways. In reality, a potato is a vegetable and will always be a vegetable, and a couch is a piece of furniture and will always be a piece of furniture.
