Remove tag but leave contents - jQuery/Javascript

Question

I'm a bit tired tonight and just can't really think how to do this simply. Basically, I have something similar to the below and I want to strip out html tags but leave their contents:

<a href="#">some content</a> and more <a href="#"> and more content</a>

and actually return the following:

some content and more and more content

Any help as always - massively appreciated!

EDIT: Thank you all so much for the answers - there I was going down the regular expression route, way to over complicate things! I actually ended up using .text() as suggested below, I've used this before but only to set, never to retrieve and it worked better as I was returning quite a large object! Thank you so much for all the suggestions :). I'll accept the answer after 6 minutes.

Answer 1

$('a').contents().unwrap()

Fiddle

Answer 2

$(selector).text() should strip out all the html.

Answer 3

This way is a little longer but maybe more self explanatory than the contents() method.

$('a').each(function () {
    $(this).replaceWith($(this).html())
})

replaceWith accepts replacement html. (not selectors)
