In this ep of "The Big Bang Theory" from last season: Leonard goes to Penny's apartment and finds a middle-aged man there. Turns out he's her father (Keith Carradine) and he's just been told his daughter and Leonard are back together. So when Penny intros them, she also plants a big one on Leonard! When Sheldon hears of this, he concludes she's "coocoo for Coco Puffs". Meanwhile, Raj and Howard are spending 13 hours at Raj's lab for some telescope sighting. Besides Indian Monopoly, Battleship, and 7 hours worth of comic books, Howard also invited Bernadette along who brought some champaign to help Raj talk to her. Actually, she brought a second bottle which may have been one too many...This is another very funny ep of "The Big Bang Theory" especially when Raj and Bernadette start impersonating Howard's mother. And what about Wyatt's (Penny's dad) going on about Leonard's positive attributes compared to his daughter's previous boyfriends especially the one who tried to get beer pong in the Olympics. So on that note, "The Boyfriend Complexity" ep of "The Big Bang Theory" is highly recommended.
