Record an evening of TV on the night of the lottery drawing one week. Make sure to record the lottery drawing also. Buy lottery tickets for the following week drawings with the numbers drawn on the night you recorded it. Invite a friend over to watch TV that night (works better if you know they didn't watch TV the week before). Ask them to buy half your lottery ticket and you'll share the winnings 50/50. Play the tape instead of actually watching the programmed TV shows. When the lottery drawing is held (on your tape) have them hold the ticket and check the numbers. Watch their reaction.

When they've left their desk, make a screen capture (print screen) of the person's desktop (preferably with a program open). Go into Windows Paint program and paste. Save as a bmp. Load the picture as the person's background. Sit back and watch them double clicking and rebooting fruitlessly. (Note: you can also create a bmp of an entire black screen and do the same. The mouse moves, but there's nothing to click on if you hide the icons!)

Obtain the telephone number of your local zoo, then give the number to the person you wish to fool and tell him/her that Mr. Lyon called and wishes you to return the call.

Going through the control panel, you reset the backgrounds to white and the text to white. The screen appears blank and can't be fixed unless you know where the buttons are located.

Turn all the clocks and watches in the house forward one hour. Spouses get up earlier for work, kids get to school an hour earlier. You sit back and relax for that extra hour.

Fill oreos with toothpaste in the middle and give it to someone to eat.

To prepare for this you need to take a video camera and record 5 or 10 minutes of video of the toilet in your bathroom. When you have a group of people at your house wait on someone to get up and go to the restrooom. While they are in the restroom play the video taped you prepared earlier and have everyone in the room start laughing hysterically. When that person comes back from the restroom, they will see everyone watching what looks to be a camera on the restroom and laughing hysterically........Then watch them blush.

make someone a cake with chocolate icing all around it but the cake will really be cornbread

Go to someones computer, do a "print screen" of their desktop. Paste it to a *.bmp and then save it in their settings as a background. They will try for hours to click on stuff that just ain't there!! Its great fun to watch. (I used to work as a PC tech and we used to do this to clients we hated)

You know the sprayer on the side of most sinks? If you put an elastic band around the push button of the sprayer, and face the sprayer forwards...the next person to turn on the faucet will get soaked. Obviously can't be done on the web, but funny just as well, as long as you don't forget and turn the water on next.

Put clear tape over the phone so that when it rings and someone picks it up, it will just keep ringing.
