When Leslie breaks up with Howard, he becomes so devastated he agrees to go with Leonard and Koothrappali to Las Vegas to cheer him up. But when they arrive, it turns out being a difficult job in itself to get Howard outside the apartment, as all he does is tracking Leslie’s online activities. Meanwhile, Sheldon locks himself out of the apartment back home and much to his and Penny’s dislike spends the night in Penny’s apartment, but he is not able to perform his daily routines and misses home.
