It hardly has any jokes in it.
Try my http://best-jokes.hotusa.org for an easy cut&paste.
Bravenet sucks. I had one of their stupid polls for a while (the 'rate the jokes' broken link). If I remember correctly, it will open two new windows, an advertisement page and the poll results page.
make your own PHP/MySQL poll. it is very, very easy to build and maintain. then you can create new polls in minutes. If I remember correctly, you were quite proud of your web hosting service; surely you must have PHP/MySQL access.
and the layout is emmm... a first draft, I hope.
oh btw. I don't think anyone is gonna submit any jokes. how many visitors do you have anyway? I bet not many, because it's very hard to get a good google listing for a jokes page.
