> This is for Achim Mahnke and Robert Krause who have a similar taste in amusing science themed T-shirts.
> They have at least two (almost) identical ones but do not coordinate wearing them at the same time.
> Hence 1st and 4th men are dancing the same pairs of figures but at differing points in the dance.
> The subtitle refers to the phenomenon of quantum entanglement coupling two particles.

> One of these common T-shirts shows a computer progress bar stopped with "Thinking... Please wait".
> For this it makes sense for the dancing men to skip the first 4 bars of a non-progressive hands across and back.
> The other T-shirt shows a Tardis crushing a car foolishly left in a space clearly marked as "Tardis parking only".
> It does not seem wise or desirable to represent this crushing choreographically,
> so instead the dancing couples move one place, in time and space, by means of a chain progression.
