To all employees...
Recently we have received credible evidence there have been seven terrorists working in your office.
Six of the seven have been apprehended:
Bin Sleepin, Bin Loafin, Bin Goofin, Bin Lunchin, Bin Drinkin and Bin but-Kissin, have been taken into custody.
At this time, no one fitting the description of the seventh terrorist; Bin Workin, has been found at your office.
We are confident that anyone who looks like he's Bin Workin will be very easy to spot.
You are obviously not a suspect at this time, so keep on doing what you Bin Doin.
Sincerely,
Bin Tellin
