This is the revised DVD special edition of this strip, with director's commentary.

This is the first time I've ever had to explicitly indicate a significant gap of time between two consecutive panels in a strip. In the original version (shown below), I used a vertical line in an attempt to indicate the discontinuity between panels 2 and 3.

Several readers wrote to tell me that this was rather clumsy and ineffective, and suggested a few other options. The simplest was so obvious I thwapped myself on the head for not thinking of it, and decided to change the strip to use it.
