Replying to Coming home from 2 years overseas and need to surprise family.

Alright NS I need some input from the creative minds here on this site. I will be coming home after serving 2 years overseas in May. I have not seen my family in that amount of time, and they have no idea that I will be coming home. I want to make it a memorable experience for them. It will be caught on tape so I can upload for you all to see. The only person that knows I am coming home is my brother so he could help me with some aspect if called for. All that we know is that we don't want to make it a public appearance, so something that involves both my parents home and surprising them. One idea that we did have was I was going to drive down the driveway on a motorcycle in a gorilla costume, or sneaking around the house setting off firecrackers everywhere. I want them to get kinda freaked out a little and make it comical. But talking to my brother about this we can't really settle on an idea. So that is where I come to you NS for some helpful ideas. Also to make it interesting, the winning idea that I pick you will win some cool Air Force swag and prizes. To help weed out the troll ideas and get some solid ideas. Thanks for the help NS and hope to see some awesome ideas. peace.
