We have a variation of this topic here. The rules in that one were a lot stricter though, so we'll probably be able to find lots, lots more solutions here.

Why did the vector cross the road?
It wanted to be normal.

Wow! Einstein was a curious little six year old!!   1 + 2 + 3 - 4 + 5 + 6 + 78 + 9 = 100
That's like something I would do now between 35 and 45 years old.

This topic is not about MySpace, nor is it necessarily cool.

And you can't 'get a MathsIsFun', either. What do you mean by 'do you have a myspace'? Do we have a MySpace account?
