Should I be Worried?

Earlier this afternoon,  when I was emptying pockets to put in a load of laundry, this is what I found in my son's jeans...

No joke, you're reading that right,  I found a whole handful of broken bone fragments in his pocket!!  Thankfully, he explained to me that he wasn't hacking up his opponents from his recess paper football tournaments.  Instead, he thought the bones that were left from the roasted chicken he bought for lunch that day were pretty cool and he wanted to save them. 

I'm going to trust him this time and not call in the CSI team, but I'm going to keep an eye on this guy and not let his cute looks fool me.

My bone collector and his sidekick!
