Identifying a Houseplant?

I picked up a large houseplant several years ago at a garage sale. Its has large leaves with roots growing in and outside of plant. The roots come from the stem with the leaves. First I tried to repot it getting the roots in, but it wasn't possible because the leaves and the roots come on the same stem. It's healthy enough, but I really would love to know what it is. The roots grow a few feet long on the outside of the plant. Can anyone help me?
