Narrative:

Demonstrating a 3 point landing on runway xx at ZZZ with two students doing tailwheel training. There was 6-8 kts. Of crosswind from the right; nothing particularly strong. Opted for 25 degrees of flaps and 60 mph speed for final. On first contact with the runway my rate of descent was a little high resulting in a bounce; then a good touchdown a little left of centerline. Airplane was tracking right so I made a left correction which didn't have enough effect. Further and more aggressive attempts to correct the track also had no effect with the aircraft increasingly weather-vaning to the right. Full left rudder and full left brake were applied and held as the airplane crossed the centerline and then exited runway 30 into the grass. As the airplane slowed it came back left and I released the rudder and brake. We came to a stop parallel to the runway. No damage to runway or the airplane; but recent rain left the grass very muddy and soft so we became stuck. Airplane had to be pushed out of the mud back to the runway with help from the local FBO.
