Does anyone have the clue for Tuesday, January 18th 2005,  I have them
all but that day.  I had to tend to my newborn and missed it by
seconds.  I even saw the beginning of the skit where they were surfing
so I know it is 'surfboard' or 'gnarley' or something surf related.  I
really appreciate anyones help on this.
