Any Suggestions for Indoor Activities in Berlin?

In the two forecasts below, one of these places in the middle of summer. The other is in the middle of winter. 

Glorious Berlin Summer

Rubbish Perth Winter

Vicky and I have some friends visiting from Perth this week. It's been piddling down pretty much the entire time they've been here. I'd like to blame them for the horrid weather, confusing the seasons, especially when last week was a little bit hot and I even wore shorts outside the house for the first time since leaving Dubai in January. I'd just be trying to stop myself from feeling so guilty, however, that their trip has been so disappointing. It's making it really hard to recommend afternoons in Prater, or Mauerpark, or the Tiergarten. Good one, Berlin.

:O

In Norway he's know as "Willy".

He's got more names than Santa Claus, this bloke.

A couple of weeks ago, I posted up a photo of Where's Wally, erm, enthusiasts near Alexanderplatz. My friendly American friend Katie advised that Wally is known as Waldo in America. Although I was originally jiggered if I knew why his name was changed, I have since discovered: he has a different name in Germany too!

Wo ist Walter?

No wonder he's so flipping hard to find all the time, and always trying to lose himself in a crowd. He's an international man of mystery! What do we really know about him, anyway? Certainly not his real name! And that outrageous get-up. He must surely be wearing it just to rile CCTV promoters: he can stand out in a crowd and still not get caught. He even wears that stupid beanie to the beach! Is he some anti-establishment revolutionary, thumbing his nose at the Man and his cameras? If I recall correctly, one of his accomplices is a "wizard". That's certainly shifty. 

Has anybody ever seen him and/or Austin Powers in the same room together at the same time?

Another Riddle

The picture below was taken in Rome, not Berlin, but Vicky was eating a gluten-free meal and I was eating a delicious no-cheese, all-mushroom pizza, so it's still blog-relevant. 

While noshing, I was utterly bamboozled as to what the sign could possibly mean. So, I have on offer a carefully hand-selected collectible €1 coin to whomever can best explain it. 

Let's hope we get more than one entrant this time...

no prize if you guess 'stop the Euro going right'

Wo ist Wally?

Right here, at the convention, planning where to hide next.

They're at a restaurant called "Cheese King"

There'll Be a Hot Time in the Town of Berlin

you know, I'm pretty sure weather.com is having me on, here

Doppelgänger

Do you ever wonder what happened to Pauline Hanson? I sure don't, so you can imagine my surprise to come across the following poster and discover that she's moved to Germany to moonlight as a cabaret singer with the clever pseudonym of 'Gayle Tufts'.

Some like it Hot! Others pray to god that it won't be.

If she's expecting Berlin to be a hotbed of ignorant racial prejudice and discriminatory immigration policies, she's 70 years too late.
