Leonard and Sheldon each lie to avoid hearing Penny sing in a production of Rent. However, Sheldon's lie becomes a bit too complicated for its own good. I love the start, with Sheldon and Leonard running away from Penny singing and then they lie - which basically starts the whole storyline off. I love Sheldon in this epsiode, actually I love Sheldon in ever episode. I love the way he freaks about the whole lying situation and then comes up with a conpletely new one - which is hilarious. I also love the way Sheldon knocks on everyones door. I also love the way Sheldon goes over the top with the lie bringing home ''Leo''. I love the way Penny believes the lie. Plus the fact that Penny makes Leonard watch her show, so the whole lying situation was pointless. Great ending.
