Is there a show next week?
Should be -- they were going to have an unbroken string of weekly shows leading up to the series finale (which, I believe, will be broadcast on a Sunday instead of the normal Tuesday).
I thought so to, Richards, but I just looked at the schedule ...
April 20
May 4
May 11
May 18
May 23 (2 hour finale; sunday night)
So it appears that it does indeed skip next week (which would be april 27)...
(unless the schedule on yahoo tv is wrong).
