Clearing list-items

To the left of this paragraph, there should be a hollow green floating box. Below this paragraph there is a list. float The list should flow around the box. The exact location of the list item numbers is debatable, the specification says they should appear effectively under the float, but this is a little silly...

1. first item
2. second item
3. third item
4. fourth item
5. fifth item
6. sixth item
7. seventh item
8. eight item
