Dumb and dumber?

The following comic seems far-fetched, but it reminds me of the story about a wife who used her new car for a few days until it could not start.

She called her husband, who came later with a mechanic.

The mechanic checked the usual causes but could not find any fault. He then said said tentatively, “Looks like no fuel flow…”

The husband then asked his wife, “Did you put in petrol?”

“What petrol?” She replied defensively, “You gave me the car, I just drive lah”
