Is this true?

Fucking is important to lots of people

I've never read a more aussie fact

There's a beer brand in Fucking, and it's a blond beer (they're called hell/helles in german), so naturally its name is “Fucking hell“

I would totally take that Fucking sign.

Actually, the one other crime reported is a case of two people fucking in front of the Fucking sign. They even put up tv cameras to deter people from doing it.

Also, the name change thing was actually a hoax that gained popularity and was reported as true. They never actually tried to change the name, according to the mayor of the town.

Amsuingly, one instance of the sign actually features a warning to motorists below it saying "Bitte — nicht so schnell!" which is German for "Please — not so fast!"
