Aquaman on eBay
James Marsters as Aquaman sketch. It's a fairly obvious mash-up, so I'm a bit surprised it hasn't been done before. It's not a bad sketch, either.
Aquaman is on the ball. Apparently a British premium of some sort. I'm tempted to bid on it. If I had any money.
As for non-eBay stuff, there have never been so many Aquaman T-shirts available. If I had any money, I'd get one of each.
