Urgent help regarding font

I couldn't for the life of me find any appropriate section for this question, so I just decided this would be good enough.
If any mod disagrees with that decision, please move it of course.

So in theory this isn't really 'urgent' as mentioned in the topic, the world won't disappear if I don't get any reply for a day or two, but I would love to get a reply asap so that I can continue with what I'm doing tonight.
Here's a picture; http://www.chazz.se/random/mysteryfont.jpg

I recognise it, I think I've used it before and it might just be a commonly recognised font; but I can't remember the name nor manage to find it.
I tried 'what the font' and I looked through several pages of different font sites and then when my head started spinning and I saw letters everywhere, I decided to just simply ask.
Do you know what font this is?

Thanks a lot in advance to anyone who replies!
