Well, on those nights when nobody's paying attention I use it to experiment with new songs to see if I know them well enough to include in my repertoire and sometimes it turns out to be fun. Nobody's listening anyway so I might as well enjoy myself. It kind of humbles your ego but that's probably a good thing - keeps you from getting too cocky! And OCCASIONALLY I'll get very involved and start singing my heart out and - lo and behold - they start listening!
