The 'deliberate' interference on the ball is certainly both uncommon and unlikely to be OBVIOUS.
I've never seen it happen.
I added it for completeness but from a little league perspective it might be more harm than good to include that possibility!
Runner stops in the path of the ball to let it hit him.
Runner swats or kicks the ball.
Obvious.
The actual rule says
"(f) If, in the judgment of the umpire, a base runner
willfully and deliberately interferes with a batted ball or a fielder in the act of fielding a batted ball with the
obvious intent to break up a double play, the ball is dead. The umpire shall call the runner out for interference and also call out the batter-runner because of the action of the runner. In no event may bases be run or runs scored because of such action by a runner;"
