How to get random coordinate within sprite collision mask?

I have a sprite with this collision mask. How do I get a random coordinate within this collision mask?

Create a new sprite. Move it randomly somewhere within your original sprite's bounding box. Test if it overlaps. If it does, you know your second sprite's X & Y coordinates are within your original sprite's collision polygon.
