Screw collection on green Pl Cr

Thank you, Dude!

Your are feeding my ignorance!

You've really screwed up this time. 

And who ever said that screws can't defy gravity?  Better still, they appear to do so by flying in formation.  By the way, the green background is both unexpected and interesting.

Thank you, Jamie, Gerald and Michael!

Michael, I consider this screwed series my best collection lately!
