If you can't be bothered to sit there constantly retrying, and happen to own a turbo controller you may be in luck.
So I just had this thought, here goes..
1.Go to options and set rounds to 1, and time to 30 seconds
2.Enter Test Your Luck mode
3.Turbo Your A button
4. Let sit while you're off doing more important things
5.Come back to your Xbox, with the hopes you got this stupid achievement
6. Repeat steps 1-5 if your luck needs even more testing
I know turbo methods tend to catch a lot of flak. So if you down vote let me know how you really feel, and see if I care
