The Big Bang Theory Wiki

Sheldon telling Penny that they lied is a page that the 4 men would use to find out latest information, probably designed by the university mentioned in "The Loobenfeld Decay".

The Website[] is part of the website that that tells you when there were lectures on.

The Lie[]

Leonard lies to Penny about having to go to a lecture to get out of her One Night Showcase of Rent. Sheldon is very anxious about the lie because if Penny was to go to, click on upcoming events, scroll down to seminars, download the pdf schedule, and look for the seminar on molecular positronium then their lie would be found out.
