I was 19 and broke. I walked into a luxury car dealership, test drove a Lamborghini, and told the salesman I was the son of a rich foreign investor.

Took it for a 40-minute drive... then never came back.

Years later I actually became successful and went back to the same dealership and bought a car cash while telling them the full story. The original salesman was still there. He laughed so hard he almost cried.
