...or have random things fall out of your mouth. I could only imagine what someone would do if you are sleeping on their shoulder, eyes open, drooling, with stuff just falling out of your mouth, like marbles, the head of a toothbrush, candy, baby fish, very small blender, or anything else small enough to fit in a human mouth.
I would have to of had the worst unimaginably horrible day to pull that one off without laughing. Ok, I might be able to pull it off, but there can't be a single person I know anywhere around or else I would just bust out laughing....

New idea, after like 5 minuites of eyes pealed sleeping and freaking everyone out, just start laughing like there is no tomorrow when the person you are sleeping on looks at you. That would be really freaky.
