Rubenstein's revenge

Rubenstein's revenge is a trick invented by Rick Rubenstein. The pattern is a repeating sequence of three throws, alternately starting with the right hand and the left hand:

The first throw is made under the arm. The arms stay crossed so that the next catch made by the hand doing that throw is also done under the arm.
The second throw is made under the arm, after uncrossing the arms and re-crossing them the other way.
The third throw is an outside throw. Rick Rubenstein does this throw as a penguin throw (a reverse penguin catch). The next catch done by the hand making this throw should be clawed.
