Easy, accept his invitation and install a keylogger into his computer via an email attachment. Get his credit card number and order a plastic blow-up doll, through an internet proxy, to one of the P.O.Box's down at the local post offices. Usually a P.O.Box is too small to house the inflatable sex-doll package so you have to remember the box number, go to the counter and say that you need to pick an "oversized" delivery. Chances are they are too busy to mind you and give you the goods.
Now with the doll, write the name of generic female woman with a black permanent marker on the front and put it outside his house, like at the front door. Do it in the middle of the night. Choose something with many syllables so it can't be mistaken for a guy in Manhattan (unless he happens to be homosexual, then go for it). He will be confused but not sure if he should bring it up to police or local authorities. He would know someone took his credit card number but not sure if he should report someone ordering an inflatable sex doll that HAPPENS to be at his house.
Now likely he would keep it under. Now at the office, casually converse with local workers infront of him and, briefly and without an indication of intention, mention how there is a "keylogger virus going around". Points if you mention how you got said "virus" and quickly know how to "dispose of it" before it does any "damage." He might pick it up and call you out to help him. Help him get rid of the keylogger and you'll probably be on his good side since you helped him out with this "private matter".
Now "birth" a female daughter. She doesn't even have to physically exist, you just "have" this girl. Name the girl the same name you wrote on the inflatable sex doll thus allowing you to use that name around the office "due to coincidences." It will unnerve him a bit every week and will keep him in check if he gives you any sh**.
That's what you should do Brian.
