PHP - 45 characters

I'm surprise nobody posted any answer that used hashing. It's a very size effecient way of testing for exact string.

echo md5($argv[1],1)!='¯è a@ÛÚƒ:ïT�p'?:42;

The data is kind of hard to copy/paste since there is a null-byte in the middle of the code. Here's an hex-dump of the code for testing purposes.

65 63 68 6f 20 6d 64 35 28 24 61 72 67 76 5b 31 5d 2c 31 29 21 3d 27 af e8 a0 61 40 db da 7f 11 0f 83 3a ef 54 00 70 27 3f 3a 34 32 3b
