Why did the tomato blush?

Because it saw the salad dressing!

Did You Know?

The joke plays on "blushing" meaning turning red, while salad dressing literally dresses the salad—implying the tomato saw something embarrassing (undressed salad ingredients). Fun fact: tomatoes are technically fruits, not vegetables, botanically classified as berries, and they turn red thanks to a pigment called lycopene as they ripen.
