Fly a German flag from a pole in your front yard. Really! People here in the USA do it sometimes. (or go European, or both if you want to treat Germany like Americans treat states)

Find something good in the news and celebrate it. I checked the news today. OK, maybe today isn't a great day for Germany, because the best I found was this: http://www.thelocal.de/20160309/firemen-free-mens-penis-from... Uh, well, it's something. Celebrate it. Germany! Germany! Germany!

Be sure to also check the French and Russian news in case a bit of Schadenfreude is called for. When you find something suitable, wave your flag and say: Germany! Germany! Germany!
