Alright I know a lot of you got Call of Duty Black Ops this Christmas and are trying to get every trophy/achievement. Check this out to get a couple of quick ones done.
This one is rather simple once you get to the main menu of Call of Duty Black Ops spam the L2 and R2 or the Right trigger and Left Trigger to break out of the chair getting the Just ask me nicely trophy/achievement. Right after you break out of the chair you can access a terminal. Once you do type DOA and get the Insert Coin trophy/achievement and get access to Dead Ops Arcade.
So there you go a simple trophy/achievement set that you can get right at the start of Call of Duty Black Ops. Good luck getting through veteran though.
