The Karaoke Conumdrum

Sheldon is worried when Amy starts breaking their dates to spend time apart, he thinks the worse when he finds out that she's been spending a lot of time with Howard...and that the rest of the gang don't appeared to be worried. Does this Doctor need to get his Texan on? Disclaimer: All characters remain the property of Chuck Lorre and Bill Prady...and are deliberately OOC!
