Because The Simpsons have been around for so long means 2 things.  You feel old when  you find out they debuted in 1989 (I was 12).  Also, it means there has been plenty of time devoted to watching, nay, tearing apart every episode frame by frame.

Is Homer Simpson dead?  Some think so!  Is Homer actually a genious? Are The Simpsons actually millionaires?

I have a theory that Bart Simpson is actually a woman!  Take THAT, internet!
