Print your code backwards - reverse quine

!hcuO

~~I actually have NO idea how it works, but~~ If you download the interpreter, and if you write !hcuO, then you get Ouch!

To run this, you need to execute the program like this:

huh.exe !hcuO

It will actually look for a file called !hcuO, but it doesn't exist, so it outputs Ouch!

Mathematica, 3 chars

a 2

a 2 means a times 2. So the answer is 2 a.

(ie \n1 where \n is the newline character)

Output:

(ie 1\n)

To quote Ilmari:

GolfScript automatically appends a newline to the end of the output

Thus a newline followed by a number will print the number followed by a newline.
