Ever had the feeling...

We've all done something and had that feeling where you think, if I had used just 1 brain cell, just 1, I wouldnt have done that.. but..

Have you ever found yourself wondering if your brain is really wired wrong? Either when you really cant grasp the concept of something you know must be simple, or that you just dont find something funny that everyone else is virtually hospitalised with hysterics over, or something??

Im having a week where I swear there must be something really really differently wrong in my head..
