Sure there is: bookmarklets, basically.  javascript: URLs can do lots
of fun and useful things.  Also fun but not-so-useful things, like:

javascript:document.body.style.MozTransform=document.body.style.WebkitTransform=document.body.style.OTransform="rotate(180deg)";void(0);

(Credit to johnath for that one.  Repeat with 0 instead of 180deg to
undo.)  You can do all sorts of interesting things to the page by
pasting javascript: URLs into the URL bar.  Of course, there are
obviously security problems here too, but "no legitimate reason" is
much too strong.
