You fool. You imbecile. You absolute buffoon. You cannot simply say "I'm gay! It's Opposite Day btw". The statement "It's Opposite Day" is paradoxical by nature. With the logic that everything said during Opposite Day is untrue, saying "It's Opposite Day" on Opposite Day negates that statement. Because the statement "It's Opposite Day" is now untrue, it is no longer Opposite Day and therefore your original remark is now correct. That means it IS opposite day, and a neverending cycle that is known as The Liar's Paradox is created. You were a complete idiot not to invoke the conditional clause. For example, if you were to say, "If it were opposite day, I'd be gay!" your statement would not be holed. You have been snared within a web of your own making. Listen to the sky crack and fall. The universe will implode on itself and it's your own fault.
