Where did all the oReo's go?

Oh MY!!! Tonight the boys wanted oreo shakes-so I went to get the cookies out of the cupboard... and this is what I found! An EmPTy oreo package. So I called the boys in...and when I told them we couldn't have shakes because someone ate ALL the cookies...both of them were glad to rat the other one out "Marshal ate them all" "Mason ate them all" is all I heard. It didn't matter none the less I just hope neither one of them have really BAD belly aches!
