If mint and chocolate aren't good enough for you, why not mint, chocolate and gold?

This story immediately has me thinking of 'Austin Powers in Goldmember,' the worst Austin Powers movie of the three.

Still worth watching if you're a teenager and you've never seen it, but make sure you watch the other two first.

This Shamrock Shake is... covered in gold.

And it's price tag is pretty blingy, too - it's been appraised at $90,000 according to NBC5 Chicago.

You can't just buy it though, you have to bid on it, for charity.

In addition to being an effort to raise money, this is also part of the 50th anniversary of the Shamrock Shake.
