Capt Wally, you are not the first to land on the wrong runway at YMMB, as a student solo, I followed a "professional" in a twin turbine thingy only to be told at the last minute to turn left and head back for 35R - the Professional landed on 31R. All the Tower said was "Oh well, it was a good landing".
Also had the pleasure, after three runway changes in 30 minutes of fluky wind changes, of going head to head with another aircraft on takeoff from 17R, seconds later the Tower saw him and there where frantic calls of "Break Right, Break Right".
