This was a question trending on twitter. It all started when a user made the comparison of "Friends with Benefits" and "No Strings Attached." After that a flood gate was opened, and we have some of the best ones.

It's funny to look at these and think how I've seen one of them, but not the other.

I'm glad Bugs life and Ants showed up on the list. These movies were made by separate studios just to spite each other.

Studios fighting leads to this a lot, but that's not the only reason this happens, other twitter users offered a reason for this weird trend.

There is also a word for this.
