Priya returns to India but Leonard and her agree to try a long distance relationship. The video chat daily and Leonard, trying to keep the spark alive, convinces Priya to try virtual sex which Leonard is not very good at. He gives it a last try, undressing in front of his monitor, talking dirty to Priya but soon Leonard realizes Priya is not the one on the other end of the video chat - it's her parents. Leonard annoyed at Leonard video chatting with Priya heads to Penny's apartment and is happy to find a new comfortable chair. When Penny tells him she found it on the street he is horrified to think of all the germs that have infested it and that are now on his body - he demands for Penny to get rid of it but she refuses. Sheldon enlists Amy's help to convince Penny to throw away the chair while Sheldon is freaking out that he has lice crawling all over his body. Amy gives it a try but Penny catches on to Sheldon's game and tells Amy to leave. Amy fearing she is about to lose her "bestie" takes back everything she just said and tells Penny she loves the chair. Amy sits down on it and both are shocked when a rat that was hiding in the chair jumps out to bit Amy. Penny begs Amy to never tell Sheldon what happened.
