"Sheldon has a revelation when he realizes why a song was stuck in his head. Also, Amy invites Dave over for dinner despite their previously awkward date, and Wolowitz and Koothrappali become obsessed with a fan of their band, "Footprints on the Moon". ""

Warning : This episode contains Shame kissing and reconcilation.

Promo pictures are here. There's actually one featuring Sheldon and Penny, although though both look utterly depressed. (who can blame them )

"Sheldon and Amy try hanging out as friends when they spend Thanksgiving together at the aquarium. Also, Wolowitz reluctantly agrees to volunteer at the soup kitchen with Bernadette, Raj and Emily, and Penny discovers that Leonard knows more about her than she thought. "

For those who are watching. The pictures and promos have been out a while so I thought I'd better start the thread as it airs tonight.

Photos here

Penny proves she doesn't give a toss about Leonard. Now THAT is funny.
