I thought the American public (and those of you who are on the opposite side of the world reading this) deserved to know the proper way to short-sheet a bed.
Trust me - it's easier with pictures. The first thing I had to do was to pick one of my dog's toys to illustrate this (I don't have kids, so there are no random barbies or dolls or GI Joe's laying around). As you can see, the dogs have issues of eating the faces off their babies. I decided to go with Mr. Lion. Even though he is flat, at least he has a face.
Start with an ordinary bed. I have colored coded this for demonstrative purposes:
The first thing you do is remove the bedspread, and Mr. Lion. Perhaps you can give him movie money, or send him out for lattes. You are left with the bottom sheet, top sheet and pillow.
The top sheet is now going to become your bottom sheet. Simply move the top of the blue top sheet to the head of the bed, underneath the pillow. The orange sheet is now hidden by the blue top sheet.
Fold the bottom half of the blue sheet to the top of the bed (simulating top sheet). You will see the orange sheet, but only in this step. You will notice that this sheet is "short" now!
Bring the bedspread back to the bed, place it on top of the blue sheet and fold the blue sheet over the top of the bedspread (just as you do when making a normal bed). This secures it.
Walk away and snicker uncontrollably.
Your friend, parent, child or whomever's bed you chose to "short-sheet", will try to get into the bed as they normally do. The "short" top sheet (turned into both top and bottom sheet) will only allow them to get their feet a few feet into the bed and cause mass confusion.
A FEW IMPORTANT NOTES:
Don't attempt to do this to a drunk person. Trust me, it will be completely lost on them. I know this from experience.
If you are married, doing this to your spouse does not work, as you will ultimately be short-sheeting your own bed.
A seasoned professional (me) can perform this in mere moments.
If you are attempting this at home, please allow 5 minutes for the first time. Practice makes perfect. There is nothing worse than getting caught.
Now go out and short sheet all beds you can!
