Flashback Friday "Where's my arm?"

OK some of you may have heard this story before, but it's a classic so you're gonna have to deal with it. (Or just stop reading because I really have no control over that, but don't stop reading k?)
So a buncha years ago my parents, sister and I were all driving to Lake of the Ozarks in Missouri. It was a LONG drive. We took the van and Jennie and I each had a bench to ourselves. We would pretty much eat, fall asleep until we ate again, and then sleep some more (Gross, no wonder I was a rolly poly).
At one point in the drive I was in the back seat and Jennie was in the middle seat. She had fallen asleep on her back with her right arm up behind her head (I hope you can get the imagery because that's essential) With her arm that way (you may need to do this yourself so you can see what she would have seen) she couldn't see it.
Anyway so there I am, watching her sleep like a creeper (I really don't know why I was watching her, but I was for some reason) and she starts to stir. She opens her eyes and I see her looking around for a second... then tired eyes turn to panic. She looks at me with fear (and a little bit of anger) and says, "Julia! WHERE IS MY ARM???" In her barely awake state of delirium she literally thought it was gone, and not only that, that I had done something with it.
I grabbed her arm from behind her head and lifted it in front of her face and let go... it was COMPLETELY DEAD and it just plopped down on top of her. To this day I don't think she and I have ever laughed that hard. Her arm had completely fallen asleep behind her head and when she woke up she couldn't feel it or see it, and actually thought it was gone.
This is one of my favorites stories. I hope you enjoyed it as much as I do, because if you didn't you need to work on your sense of humor, cuz it's funny crap!
