What is the best way to set up Mime Mouse on someone's computer?

Wait for the victim to leave their desk, then quickly run Mime Mouse. It starts instantly and hides in the background with no visible window. When the victim returns, their cursor will periodically get trapped in an invisible box. Watch from a safe distance as they try to figure out why their mouse keeps getting "stuck." For best results, act puzzled and suggest they might need a new mouse.
