Haha,
HAPPY BIRFDAY MI_KEYS...its always a good time.
Now to sound like a parent...seriously be safe.
True story* My 21st birthday- I woke up face down on my thrown up shoes (I wore out that night) under my futon...not ON it...under it. Didn't recall a damn thing other than my gf (now my wife), her best friend, and my best friend laughing at me dry heaving and farting at the same time over the toilet. I woke up with a huge stain on my shirt because I decided to keep all 17 plastic shot glasses in my shirt pocket....
I am sure some of the people here have better 21st birthday stories than that!
Have a great time, I hope you have great friends to celebrate with!!!
