Vatertag is also Ascension here (or the other way around), and a real holiday. And a real boon to the German liquor industry, too.
And there really is some connection between the two holidays here somewhere, I think. Jesus is known to have drunk wine and wander around the countryside with his buddies, for instance. Although without the Bollerwagen (handcarts), of course. Nor did they ever drink and drive, as far as I know.
Not so here in Germany, however. Bild tells us that there will be three times as many alcohol-related accidents today as usual. And I believe it, too. Just ask these guys down here.
Herrentag ist Unfalltag!
PS: Christi Himmelfahrt is the Ascension. A Himmelfahrtskommando is a kamikaze operation.
