But where do all of the Paci's go?

I am completely convinced that Paci's end up in the mystical place that the missing socks go to. Seriously, where do they go?! I just bought Baby A two new packs of Paci's last week and for the life of me, I cannot find two out of the four. So where do they go? I've checked under the couch, the bed, the crib, the dresser, the entertainment center, the table, in the car. They're no where! Every once in a while a missing paci will show up here or there, I assume that Baby A has hide them somewhere but for me, this place is still a mystery.
