The level was about 1/4 inch or so above the MAX dot thing.....so probably not too much but I was still a little concerned. I went back and had them take out about half a quart and now the level is perfect.
I had never heard of this happening either before it happened to me. There is one certain lube shop in my hometown that overfills all the frikkin time. It happened to me there once....and it's also happened to everyone else I've talked to that went there. Needless to say....none of us have gone back there again.
Anyways, thanks for the replies everyone. And that horror story.....ten quarts in one engine

.......yikes!
