Perhaps you could impress upon them the need for some amount of code optimization? Basic stuff - "If you have seven roll-over graphics, you can control them all with ONE function" or "The pop-up will still work without the seven lines of comments the page editor macro put in to explain how it works."

Even better - which JavaScript functions are MSIE extensions and which are Netscape extensions, and why one does not work on the other.

BEST - Client side PerlScript! :)
