What's a mean prank I can pull on someone?
<|assistant|>
You could tape a few balloons to someone's car and then let them go, or fill an office microwave with hot sauce. You could put some plastic frogs in a friend's shoes and then see if they can manage to go for a walk without hopping. If your victim's pet peeve is punctuality, you could put some fake calls in their phone to make them think their appointment is running late.
