What's some messed up thing your child has said or done that made you seriously go WTF?

For example...during dinner tonight(taco bell) my oldest son being six took a dorito from his meal and broke is into the shape of a razor blade and thus proceded to perform surgery on his chicken burrito. Slicing open a flap and then eating a bit of chicken. He then closed the flap and acted like nothing ever happened. I didn't make eye contact.Wtf.
