Sound

Create a unique sound experience by replacing a colleague's mouse or trackpad with a custom-made, squeaky version. For extra effect, attach small rubber 'feet' to the bottom of their chair, ensuring they squeak every time they stand or sit.

Don't forget to record their initial reaction, but ensure you have their permission first, and they're in on the joke soon afterward.

Sight

If you share an office space with a clean freak, swap their monitor with one that appears to have a smashed screen, complete with convincing-looking cracks and smudges. Their initial shock will turn into laughter once they realize the truth.

Use a spare monitor or a simple piece of transparent, cracked plastic stuck to a real one, ensuring no actual damage is done.

Halloween pranks are an excellent way to lighten the mood and strengthen bonds between colleagues, friends, and neighbors. Just remember to keep it fun, respectful, and safe. Happy pranking!
