Pranks you could pass time w/ and get a good laugh at someone you know!

Under The Door Pranks
Fill an accordian folder with shaving cream, insert under someone's door and stomp on it which will send large amounts of shaving cream into their room withought ever opening the door. Also can be done with a fine powder (Talcum powder works nicely) in a bag with a hole in the bottom. Slip the open end under the door, stick a hair dryer in the hole and the room gets a nice sugar coating.

Funny ID
Use some temporary glue such as a glue stick to put a picture of a monkey or anything else that would be funny over your roommate's photo ID or drivers license. Then ask him to go make a beer run. He will have to show his ID to the cashier to identify his age. This trick could also work on a school ID, just send him to the library to check out some books.

A Few Pounds Heavier
Go out and buy some new boxers or underwear. Buy the same kind and brand that your roommate wears. Only be sure to buy them a couple sizes too small. Wash them a few times so they don't look brand new. Then replace them with his old ones in his drawer. When he tries them on and realizes they are smaller than usual, he may think he put on a few pounds and is heavier.

Dude! Youre Glowing!
Pour "cyalume" (the stuff in those glow sticks you see every holoween) on someone then wake them and say, "Dude, you're glowing" and watch them panic.

Where Is The Alarm?
While your victim is alseep, reset their alarm clock so it goes off at 2am or 3am. But don't place it back on their nightstand. Instead hide it in a closet or behind the tv. The person waking up will be on an early morning hunt for where that annoying sound is coming from. For even more laughs, try unscrewing the lightbulb and watch the person scramble around the room in total darkness.

Beach Towel Prank
When your victim leaves his or her towel, quickly dig a hole in the sand and place the towel over the hole. When your victim returns, he or she will 'fall' for your prank while you sit there and laugh.

Clear Tape Prank
Place clear tape across the outside of a door from top to bottom (saran wrap can also work). Frequently people will run into it especially if they are in a hurry. If the door is metal and has a metal frame, weld the person into (or out of) their room. Can be done to the hinges as well if there is no metal door.

Palms Down Beverage Trick
Impress your friend and show him how you can balance 2 cups of liquid on your hands (palms down). Then bet him that he cannot do it. When he tries to do it, offer to help him...once he gets it and balances the cups, walk out of the room and leave him to figure out how to remove cups from back of hands.

Keyboard Difficulties
Write a TSR that turns the keyboard on and off at short intervals. You'll watch the person try keyboard after keyboard. Can also swap keys using ANSI.SYS or xmodemap depending on the system.

Black On Black
Change the prompt on someones computer to be black on black. This is rather cruel if the person is computer illiterate. Very effective the day before a big project is due.

Sorry About The Damage!
Leave a fake note on someone's car windsheild that reads, "Sorry about the damage i caused to your automobile. Call me and I will be more than happy to pay for the repair" Be sure not to leave a phone number...of course there is no real damage. But the victim doesn't know this. He or she will look all over for a dent or scratch or something.

Shampoo Shower Prank
Glue a bottle of shampoo to the shower shelf (to avoid damage, use clear caulk on a surface that can be scraped).

Bar Of Soap Lather Prank
Take some nail polish and coat a bar of soap with it. Let it dry. Then put it in the bathroom shower. When your victim tries to use it, he or she will go nuts trying to get it to lather up.

Restroom Hand Dryer Prank
Flip the open part of an automatic hand dryer up and pour some dye powder inside. Make sure to get it deep inside the little heater part. Now flip it back down while holding a napkin up to catch any loose powder. The next person to use the hand dryer will end up with dirtier hands than before he washed them with water.

Poo On The Toilet Handle
Smear some melted chocolate on the toilet handle in a public restroom. Everyone will think its poo instead of chocolate and will try to avoid flushing it.
