For twenty minutes:
10 Dumbbell Thrusters
10 Pull-ups
Multiply thruster load by rounds completed, e.g., 50 pounds X 23 rounds = 1,150 pound-rounds (a useful measure of work and, by extension, average power for the workout) and post to comments.
Use false grip and bring the rings as close to your navel as you can. If you don't have rings, do pull-ups and dips - lots of them. Post results to comments in both cases.
