Some guy sent about 1,000 BTC and he included a 0.005 tx fee.
This is that transaction:

Output $ 376,352.59
Fees $ 1.79
That kind of transaction fee for that kind of money sent is indeed ridiculous! He just sent over $376,352 over the internet to what may eventually end up being over a thousand different people, without opening an account anywhere or asking anybodys permission. That transaction was completed and confirmed in about six minutes, and it cost about fifty cents in transaction fees at that time.
Ridiculous!
I find it very interesting that all of the addresses this person sent BTC to started with '1Ag'; I somewhat suspect that this person has hashed several addresses and sent this bitcoin to himself.
You suspect well. This was one of Casascius' coin-loading transactions. This particular transaction corresponds to a stock of silver rounds (note that the chemical symbol for silver is Ag).
Ahhh, at first I thought it was some kind of pool like payout (or some other similar payout), then I started to notice that all of the addresses were somewhat similar. (LOL).
IMO it would have been realistic for them not to have included a TX fee at all as they should not have been in any kind of rush to get the TX confirmed (they likely had days before the BTC "had" to be confirmed), and could have split up the transactions into smaller TXs as necessary
