When somebody knocks another person unconsciouss and steals their clothes,they always fit perfectly.

When people are being chased by cars,they run down the middle of the road and keep looking back,rather than just getting somewhere safer.

When somebody kills a bad guy/monster they walk away instead of finishing him off.(and we just know he is coming back)

Bombs always have handy LED numbers on them,and they are never going to be made safe until the counter shows a few seconds left before detonation.

any more?
