Switch just a couple of seemingly innocuous keys on their keyboards or calculators, M and N for instance.
I pulled this on my boss-I switched the keys on his calculator to resemble a phone keypad. Even though he was a CPA, he did look at the keypad occasionally while doing his books and couldn't figure out why when he hit one number, another one came up....took HIS boss coming in to figure it out...while I left the office and got hysterical laughing.
The classic is hiding a single shrimp really well and letting the smell drive them nuts...
