Slab', yours reminded me of one I pulled on fishing friend Dave long ago. He was always hyper-concerned about drivers falling asleep on the way back from fishing trips (which isn't such a bad thing). One time coming back from Tillamook he had asked me how I was doing for about the 3rd time before we even crossed the coast range summit. I told him I was just fine, and on this trip I wasn't nodding at all; so he let up and started looking a river views out the right side of his passenger seat. Approaching a long sweeping right curve I leaned my head against the side window and closed my right eye, leaving the left one open. Coming into the curve I kept going straight into the oncoming lane; carefully with my left eye open and no cars coming. Dave freaks and does a combo of yell and grab the wheel at the same time. It was funny at the time but I wouldn't do it again to anyone; not smart.
