Random geeky things you've done

[Evil_Maniac From Mars]

If want to equal my amazing deed Mr. Smartypants, name every German state and its capital. And don't look them up (though it would surprise me even if you looked them up).

With English names as a courtesy to the forum's main language.

Baden-Württemberg - Stuttgart
Bavaria - München
Thuringia - Erfurt
Schleswig-Holstein - Kiel
Saxony - Dresden
Saarland - Saarbrücken
Saxony-Anhalt - Magdeburg
Berlin - Berlin
Bremen - Bremen
Brandenburg - Potsdam
North Rhine-Westphalia - Düsseldorf
Rhineland-Palatinate - Mainz
Lower Saxony - Hannover
Hamburg - Hamburg
Hesse - Wiesbaden
Mecklenburg-Vorpommern - Schwerin

If I have any of those wrong...
