fastest way to get the checked radio button using jquery

Question

I wanted to get the selected radio button and display the text that corresponds the radio button using jquery.

<div id="Poll">
    <div id="PollQuestion">Your favorite color?</div>
    <ul>
        <li class="liAnswer">
            <input type="radio" value="1" name="Answer" class="clsAnswer"/>
            <span>Red</span>
        </li>
        <li class="liAnswer">
            <input type="radio" value="2" name="Answer" class="clsAnswer"/>
            <span>Blue</span>
        </li>
        <li class="liAnswer">
            <input type="radio" value="3" name="Answer" class="clsAnswer"/>
            <span>Green</span>
        </li>
        <li class="liAnswer">
            <input type="radio" value="4" name="Answer" class="clsAnswer"/>
            <span>Yellow</span>
        </li>
    </ul>
    <input type="button" value="Submit Vote" id="btnVote"/>
</div>

First, check if there is no selected color and then display the selected color and the corresponding value.

How can I do that?
