So simple, but so irritating!  The best part about this trick is that it's a slow burn.  One day you notice a little green thing sprouting through your keyboard, then the next day, there are more... and more... and more.

You could also go all in and cover their entire office with sod, like these guys did.

Public Service Announcement: Don't try this one if your coworkers have a heart condition, unless you feel like taking a ride in an ambulance today.

Alternatively, you could attach the air horn to their office chair, like a much louder and more intense Whoopie Cushion.
