Moon- there are plenty of people who walk a lot and work out "once in a while" who aren't skinny. I'm sick of people taking credit for what genetics is handing them.

Don't Keplerian telescopes invert the image?

but does it come in gay flavor?

Oh yay! I flipped out when I saw that place in Berlin and then my camera immediately died. I'm so glad I have a photo of it now! (Though judging by the comments, I guess I could've just googled it)

Lots of good suggestions up there!(you have to do the Brandenburg gate!) I say try Currywurst AND Döner - Problem solved. If you want to get an overhead view of the city/part of the city, you can go up the Chrysler building in the fastest elevator in the world. It's a red/brick building across the street from Potsdamerplatz - which you will probably go to whether you like it or not. I also liked the giant timezone clock/sculpture the "Weltuhr" in Alexanderplatz. The East Side Gallery is a MUST see - a long, standing section of the Wall. Which reminds me, I think you'll appreciate the city more if you know a bit about the history of the division/Wall (I'm a German studies major, and I cried at the Brandenburg gate). The Neue Wache memorial near Humboldt on Unter den Linden is incredibly moving.

"Brauhaus Mitte" in Alexanderplatz is a delicious brewery/restaurant if you feel like doing the "I'm in Germany, I'm going to try German food!" thing.
