You may have to buy the DVDs to get those episodes legally. Surely, you don't expect people to post ways to get stuff illegally and to violate the producer's copyrights?!

well, I did just see a thread on someone asking how to get House episodes online, and plenty of people were responding to that.
You could try looking on hulu.com if you're in the US, they legally stream TV.
The show was put off the air a few years ago, Hulu most likely won't have it.
