Binkies AKA Pacifiers

How the hell do you go from 100 binkies to 2? I just bought 2 packs (2 per pack) and am down to 1 pacifier. I don't know what my son does with his pacifiers! The last 3 I've given him are when he's been laying down in his playpen and I can't find them in there. I know when he's in his crib he spits/throws them over the side but I can't find them anywhere near the playpen! Anyone else have that problem? Also does your kid like to bend the nipple and put like half the pacifier in their mouth and chew on it? Drives me nuts..
