Narrative:

I was cleared to take off on what I heard was runway 29R, and asked to expedite! I repeated takeoff runway and complied. Local control said abort and clear the runway after the takeoff roll started. I maneuvered the aircraft off the right side of the runway. Local then ordered the jet on final to 'go around!' I was then instructed to re-enter the runway, taxi to a near-by exit and proceed to runway 29L where I was cleared to takeoff. Local said I was cleared to cross runway 29R and takeoff on runway 29L! I replied that I repeated the assignment as runway 29R and expedited per instructions. A classic example of misunderstanding instructions. I'm embarrassed but alive!
