Mindfuck moments, games, videos.

[Romulator]

Though not always mindfucks, Philosoraptor memes mainly use paradoxes

Some of my favorites of those are:

The next sentence is false
The previous sentence is true

If nobody uses the school toilets because they are dirty
Doesn't that make them clean?

If every girl says they're not like most other girls
Doesn't that make them like most other girls?

If I choose to lose, and succeed
Am I a winner?
