First of all, search for The Simpsons, season 22 in iTunes (ad free HD totally worth the $3,50 in my humble opinion).
Ad supported (but legal and free):
-Desperate Housewives (CTV)
-Big Bang Theory (CTV)
-Modern Family (City TV)
-Moderation Town (Showcase)
-Infoman (meilleurs moments) (in French) (SRC)
Happy laughing. :)
