I remember, I had a REALLY fun Christmas surprise once. Or, rather, it WOULD have been a surprise if my mom didn't fail hard at hiding games.
One day, she came home from Walmart, and asked me to go to the car and get the stuff out of the trunk. I did so, and as I did, I noticed a game, by itself, in one of the bags: Final Fantasy X for the PS2. I didn't own a PS2.
So, very calmly, I walked in the house, with the game behind my back. I walked up to my mom, and asked her, "What's this?", holding the game in front of me. She stared at it for a few seconds, before saying, "************!". I was SUCH a little troll

.
So, as expected, I got a PS2 for Christmas, with Final Fantasy X, and Grand Theft Auto: Vice City. Epic times were had.
