Python (27 characters)

In the Python shell, the following script will output the desired result:

TzoubyFssps;!jowbmje!tzouby

Yes! it outputs:

SyntaxError: invalid syntax

huh?, 5 characters

Ntbg 

Note that the 5th character is a space after Ntbg. This is the same trick as in one of my previous answers. Ntbg is an invalid path, so the interpreter will output Ouch! You should run it like this:

huh.exe Ntbg 

PHP (351)

I'm sure there's a better way to do this, as I am new to codegolfing, but here's my PHP solution:

function q(){$q=chr(39);$a=array('function q(){$q=chr(39);$a=array(',');@$r.=$a[0];foreach($a as$b)$r.=$q.$b.$q.",";$r=substr($r,0,-1);$r.=$a[1];for($i=0;$i<strlen($r);$i++)$r{$i}=chr(ord($r{$i})+1);return $r;}');@$r.=$a[0];foreach($a as$b)$r.=$q.$b.$q.",";$r=substr($r,0,-1);$r.=$a[1];for($i=0;$i<strlen($r);$i++)$r{$i}=chr(ord($r{$i})+1);return $r;}

Output:
