Wobbly Macbook Pro

I bought a MacBook Pro yesterday, and it's "wobbly". My front-right leg is about 1 mm or so shorter than my back-left leg.
Is there a quick fix for this (I was thinking of just making it bigger by myself) or should I send it back to Apple?

Most times I have seen this, the table is the thing not level. Does closing the lid and rotating it ninety degrees with the apple logo staying over the same spot actually move the short peg or is the table the issue?

I suggest taking it back. I suspect that the bottom plate with the legs on it wasn't attached properly (it can flex a bit), but if it's a brand new device it's easier just to get it replaced than to try to fix it yourself.
