I got to be a guinea pig once for training officers on field sobriety testing. Sat in a hotel room with 5 other people and a couple cops, they fed us booze n food for 4 hrs. then took us downstairs where there were about 100 cops, split us into groups where the cops would field test us, all the while not knowing how much each of us drank, I was pretty smashed, failed misserably every time, and completely hung over by 6pm. Lotta fun I think.
