Why boys, why? :The Case of the Rose Stem

Almost everyday I come across something in my house that has me stumped.  I am so glad the boys can be creative, but there are times I am completely baffled by what they could have been thinking.  I  am going to start taking pictures of what I come across that has me asking, "Why boys, why?"  Here is our first:  The case of the rose stem.

Here we have a rose stem stuck in black modeling clay with an Iron Man mini-fig chest on the front.  This is stuck above the cabinets in my kitchen.  I really cannot guess what this could be for. They really do keep me on my toes.  Happy Weekend!
