So when you see someone else today, give him or her a big hug and wish them a Happy Franz Ferdinand Day. When he or she gets that big blank expression and goes "Huh?", tell him or her that on this day it is tradition for people to go around hugging each other and eating large chunks of apple pie. Then insinuate that the person who has been hugged is supposed to supply the said apple pie, and suggest that he or she go fetch an extra large one immediately. Then solemnly contemplate the lives lost during World War One while eating that nice big apple pie. It does good things for the soul, trust me.
Don't you just love history?
