For a number of years myself, George Krumins, and my friend Charles Guy 
have been working a play called the Big Boys Squirm.  It has three acts.

First comes the Big Bang.

Second the Steady State.

And finally, the Big Crunch.

These are three competing models of the Universe.  The Universe is
probably expanding forever, so in reality the Big Crunch will never
happen. 

But in the play the wheelchair loaf introduced in the second act has an
analogue in the third act with the Big Crunch(TM) candy bar.  The
wheelchair loaf gave Hawking (one of the Big Boys of cosmology) the 
power to stand and speak in his own voice.  In the third act the candybar 
gives him the power to fly.  But there are dire consequences...
