How to delete ALL notes from Stickies app?

Eventually I need to clean house when too many Stickies notes accumulate, but it seems harder than necessary. Is there an easy way? Mac OS allows many windows to be closed at once using option-command-w (Finder Get Info windows, open folders, open Preview windows (even if edits have been made)). But this does not work with Stickies. And since they all have content, you get prompted to save every time command-w is used. So the only way I know is to command-w, spacebar, command-w, spacebar, command-w, spacebar, etc... As you can see in the animated .gif, this gets old. Is there a better way?
