3 drunk guys got into a taxi.
The taxi driver knew that they were drunk so he started the engine and after a few seconds, simply turned it off again.
Taxi driver: We have reached your destination!
The first guy gave him some money and the second guy thanked him as they clambered out of the car.
The third guy slapped the taxi driver across the face.
The taxi driver was shocked, thinking the third guy was drunk.
Taxi driver: What was that for??
Third guy: Control your speed next time, you nearly killed us!!!
