A Hammogram is the sexiest Jon Hamm-related Valentine's Day gift on the planet earth. A friend and/or lover will send another friend/lover a Hamm-O-Gram, which is a mailed envelope. Inside this envelope is a handsome picture of Jon Hamm and a love note, both of which have been dipped in aftershave and glitter. Effects of a Hamm-O-Gram include extreme horniness and MAD MEN marathons.
Dwight sent me a HammOGram for Valentine's Day, even though he knows I'll know be thinking of Jon Hamm whenever we do it.
