What is the best way to set up the Add/Remove prank?

For the best reaction, try these tips:

• Copy the .exe to the target computer's desktop or a folder they use often
• Rename it to something they might click, like "System Update" or "Important"
• Be nearby to watch the reaction when they click OK and the removal animation starts
• Let the prank run to completion before revealing the joke -- all their programs are still there
