It's a case of the thrust line being well below the center of mass.
World Airways had just such an incident in Anchorage few years back doing a ferry with # 2 engine inop. Although they followed Boeing procedures, ( which called for setting takeoff thrust on 1/3 before brake release) the center gear had been retracted changing the cg, so the aircraft immediately did a wheelie and tail strike.
