A1 and B1 are in a loose ball situation and both are lying on the court. A2 then sees an oppurtunity to gain possesion but with 2 bodys already on the floor, A2 falls to the court also. A2 then rolls over to get up and is sitting on the ball (like hatching an egg) with both feet on the court. A2 then takes both hands, grabs the ball on which he/she is sitting and stands straight up without moving a single foot and then procedes to dribble down the floor. One in a million chance this will ever happen to you but I was just curios with what you thought?

If only his feet are touching the floor when he picks up the ball, the play is legal.
