Why we cannot have company over

Last night we had a couple of our church missionaries over for dinner.  The boys were OK until the end.  Squirt decided that the missionaries needed ketchup on their chicken tetrazinni. So he took a tomato from the salad, chewed it up and spit it on one of the their plates.  He was really proud of himself.  His defense is that chewing tomatoes is the fastest way to make ketchup.  The parents were grossed out and the missionaries were good sports.
