I spent Father's day helping other people with their computer problems. "You have to find the Windows XP setup disc I explained over the phone." In the real world, fathers spent the day eating and opening boxes filled with ties and analog television adapters. I always gave my father a stick of Old Spice deodorant. More fun is what they do in Eastern Germany.
Here, according to Wikepedia, in Eastern Germany they call it "Men's day" and it's not limited to fathers. Here, the men all get drunk and ride around in wagons. (Go to section on Germany). Sounds like more fun than yelling into a phone, "No not the drivers disc, the setup disk!"
