But I'm pretty sure this must be what it feels like.
You take one body and you crash it. Then you deprive it of sleep for several days while a child has the flu. Install the latest version of that flu virus on the body's hard drive, deprive said body of it's daily caffiene intake and rack the abdominal muscles with convulsions. Be sure that the virus you have downloaded makes it impossible to ingest any kind of pain reliever.
When all is said and done you should look like this.
And feel like you've been run over by a garbage truck. I swear if I hear the back up beeping I'm just going to lay down and let it take me.
