Summary: Leonard cleans up after an Internet experiment, and in the trash can he finds an invitation to him and Sheldon to present their joint research at an academic conference. Sheldon disapproves of presenting research in person, but Leonard defies him and goes alone. This causes a rift between the two which Penny tries to mend but accidentally makes worse. Sheldon appears at the conference and tries to discredit Leonard's presentation by attempting to "blow up" Leonard's head with his mind à la the movie Scanners, starting a physical altercation between the two. Howard films the fight on his cellphone and puts it on YouTube, but angers Penny by also posting a photo on Facebook of her sleeping on his shoulder during the presentation, entitled "Me and my girlfriend".
