I'm very curious as to how this non-standard transaction made it into the blockchain. I have two guesses: 1) Whoever did this has access to enough hashing power to mine their own non-standard transactions into blocks. 2) $0.43 is unusually high for a transaction fee. Perhaps this is high enough to incentivize miners to include the tx in a block.
