Fancast
OK, I may be the only person who had never heard of Fancast before but just in case I'm not, I'm going to tell you about it. It's a free site where you can watch TV shows. I was looking for a place to watch the season finale of House (which I had recorded for Andi and Big Guy then accidentally recorded over before they saw it), when I found this site.
Not only can you see House and other current shows on it, but dozens and dozens of full length episodes of some of my favorite shows -- and I'm not talking only current shows. FROM YEARS AGO. Shows like Family Ties, Nanny and the Professor, Picket Fences, St. Elsewhere, Chicago Hope, McHale's Navy, Major Dad, Hill Street Blues, Simon and Simon and one of my absolute favorites, The Dick Van Dyke show.
You can bet that Fancast is bookmarked on my computer for future use. Future as in this afternoon after school :)
