Do you have a significant other who is hard to shop for? Then you just might like to get them one of these subatomic particle plush toys. To show them you really care, you could get them the whole Lepton 6-Pack, or even the whole set with antiparticles! (If you are in a hurry, I think the tachyon ones arrive before you order them.) Don't forget the Quantum Chromodynamic dots to hold the quarks together...
I have not figured out if this site is a joke yet, but they do appear to accept money. Happy shopping.
