Zone out most of the morning, with 3 or 4 large cups of coffee. Close my office door and web surf till 2 pm or so, read most major newspapers, gambling forum sites, "news of the Weird" etc
maybe about 15 min of actual work completed by days end
If you feel the need to wonder around the office like the sudden urge to glance again at the office secretary or the office hot chicks cleavage, be sure to carry a sheet or sheets of paper in your hand. Make's it look like your up for a reason doing something like making copies or retrieving a fax. Paper is like a hall pass at work.
