Episode The Loobenfeld Decay.

The rock musical Rent with music and lyrics by Jonathan Larson is loosely based on the Puccini opera La Boheme about a group of impoverished young artists struggling to survive and create in New York City. Starting as an off-Broadway production, it opened on Broadway at the Nederlander Theater on April 29, 1996, and closed on September 7, 2008, after a 12-year run and 5,123 performances. The original production won both a Tony award for best musical and a Pulitzer Prize. In 2005, it was adapted into a motion picture featuring most of the original cast members.


It was a one night show and Penny thought there would be a lot of casting agents. Leonard lies to Penny to get out of it.


The song Penny was singing was called "Out Tonight", a song in the musical "Rent".

The lie could be uncovered by if she were to log on to, click on upcoming events, scroll down to seminars, download the pdf schedule, and look for the seminar on molecular positronium.

By the end, there were only two people.
