Putting Cats in "Time Out"?

Very funny video! I think kitty time outs are great. I'm currently trying to teach my cat to stay off my tables. She gets anywhere between 15 - 30minutes in the cat room which is a short hallway leading to my basement. The only problem is she goes there so frequently that I think she's starting to like it. So I need more ideas for discipline because my feline friend just seems to get used to whatever I do. Believe it or not she's even gotten comfortable with being sprayed with water. I've got me a renegade cat.
