I just had to see these while at work... ugh.

[_vd_]

So these hurt my head.  Many are funny.  All are unsettling to some degree.  Very few are actual metaphors.  Okay, none of them are... still, I recommend numbers 2, 5, 6, 19, and 20.

Supposedly, these came from high school students.  I weep for our educational system and fear I will get to the classroom too late to help anyone.
