I think the funniest thing about the episode was my new favorite phrase:
"What? Do you have sand in your vagina?"

I own the 36xbr400 and I am about 8-9 feet away. Perfect size! I would be disappointed in anything smaller and I compared bigger sets and found them difficult to watch that close.
I watch a combination of regular cable and DVDs. Not too big for regular tv and just right for letterboxing...
