Can someone explain this play to me?

So...I decide to work off more bonus hands on PP, drop into a table right behind the button and pay for th ebig blind on a whim....I NEVER usually do this, I wait for the BB to come to me....gut said to do it and I get AA....Happy as a clam. Did I miss play this along the way somwhere?
