Repetition, Baby

Why is it every night, sitting down to watch TV with Will, it's one of the same three episodes of The Backyardigans?  I know that toddlers love repitition, but seriously!!  :)  I know them from memory....the "secret Agent" one, the whodunnit mystery and the one with the mermaids.  He loves it though, so I'm just along for the ride!
