Find an element in dom with jquery

I'm trying to write a bit of script using jquery that will return the h3.the-thing-title text where the sibling selected option value is 6.  In other words I'm trying to get h3 text where the adjacent select has 6 selected.
$('.blue').find('.house-number[value="6"][selected="selected"]') and it's not even close to working.  Any ideas how
I can do this?  I just need to get the h3 text which would be Derp 2 in this case.

<div class="blue">
    <div class="the-thing">
        <h3 class="the-thing-title">Derp 1</h3>
        <div class="col-four">
            <select class='house-number'>
                <option value="0">Zero</option>
                <option value="1">One</option>
                <option value="2">Two</option>
                <option value="3" selected="selected">Three</option>
                <option value="4">Four</option>
                <option value="5">Five</option>
                <option value="6">Six</option>
            </select>
        </div>
