Adventures in Nesting

<p>         
    <object>
        <p>foobar</p>
    </object>

Yes — that's right. A paragraph within a paragraph. It validates too, but it's a nasty hack.

An alternative would be to use NOSCRIPT instead of OBJECT, but then this text would be hidden for most people. APPLET works too, but doesn't seem quite as reliable.

Valid HTML 4.01!

It validates, but that doesn't mean you should do it!
