Why Grandpa needs a Pacifer (not the kind in a bottle)

I have been in the handy husband mod the last couple of days, repair the shower drain, fix the door lock, etc. If you're long time married you probably know the routine. One one of my trips I noticed a smashed baby's pacifer lying on the pavement. Being a good citizen I picked up the remains and threw in the back of my pickup. I guess I'm telling you all this so you don't think I'm snatching babies pacifers. Today I had an an idea that panned out. I think the photos are self explanatory.
