 
One of the funniest shows in tv history has started airing weekdays/nights on CBC. 
Arrested Development is airing Monday-Friday at 5:30 and midnight local time. It's airing in HD at 3:30 and 10 (Calgary time).
This is one of the few shows that is actually funnier upon second or third viewing.
The pilot episode aired on New Year's Day (it will air again at midnight), and the other episodes are airing in order every weekday.
I already have every episode on DVD, but I haven't seen any in HD.
