Happy Days season four started on Sunday showing three episodes every sunday (So Sunday was eps 1,2,3 and next sunday is 4,5,6 and so on and so forth)... However on the 1st which is a Thursday early in the morning their is an episode and i was wondering if thats part of season four? Also do they normally have marathons? Is their anyone in the know who has got info on a Marathon airing on TV 1 soon?

Thanks.
