My new favorite line of JQuery

//alternate row appearance
$(“table > tbody tr:odd”).addClass(“odd”);

A close runner-up is this:

//bump up the contents of cells by removing first BR
$(“td.list-of-stuff-delimited-with-br”).find(“br:first”).remove();

I normally would handle stuff like this on the server side, but these save me the trouble, and considering it’s a presentation layer thing, doing it on the client just feels right.
