*two friends in the middle of a race in a racing game*

Friend A: Good luck winning, my car has the best engine.

Friend B: Not if it brakes down.

Friend A: Nah, its the most reliable engine as well.

*Friend A's engine brakes down litteraly 2 seconds later*

Friend B: Well thats the Viner Effect for you.
