fell off the turnip truck

Born yesterday, apparently

To fall off the turnip truck is to arrive somewhere naive and unsophisticated, like a country rube who literally rode into the city on a vegetable cart.

Almost always used in the negative to assert one's worldliness: I wasn't born yesterday—I didn't just fall off the turnip truck.

The phrase implies the speaker can't be easily fooled or deceived.
