A simple surprise for your office is the classic plastic mouse. Hide it under someone’s monitor or under a stack of sheets and let the fun begin!
Tip:
If you get a small plastic mouse (like mine) then you won’t totally freak someone out. In fact, the receiver might even think that it’s a cat toy. Personally, I’d opt for a larger, more real mouse to create that authentic surprised screech.

forget the plastic mouse. Do the trick with a real mouse! Ha! Can you imagine the fun!
Someone did something similar at work … they brought their Pomeranian in! “Be careful you don’t roll your chair over it!”
