If I'm riding a road bike, i unclip with my left foot (i'm right handed)

If i'm riding my mountain bike, it just depends on the terrain and sometimes when you have to get out quickly, so I can unclip either side, any time. I can't clip in backwards though or I don't think I've ever tried. What I mean is I start clipped in with my left foot and then mount the bike and clip in my right foot.

Oh, I guess there is one exception to the clip in thing. When I am doing cyclocross, I jump on the bike unclipped so when I swing my foot over the bike and slide down, I guess I do clip in first on the right side since that is the pedal that is up and I engage that pedal first.
