In the sitcom world, The Big Bang Theory reigns supreme. Put your knowledge of Sheldon, Leonard, Raj, and Howard to the test!

While Friends and How I Met Your Mother are icons, they don't overshadow The Big Bang Theory, which premiered on CBS in 2007. Dive into the quirky lives of Leonard and his eccentric roommate Sheldon—the ultimate "nerd" duo obsessed with video games, sci-fi, and comics. Joined by loyal friends Howard and Raj, their world flips upside down with the arrival of their new neighbor, Penny.
Life for these science-obsessed roommates, fueled by comics, epic sagas, and games, gets hilariously complicated when Penny moves in. This clash of worlds spanned 12 unforgettable seasons. The Big Bang Theory beautifully illustrates that "opposites attract" and love conquers all.
Penny, masterfully portrayed by Kaley Cuoco, challenges her neighbors Sheldon Cooper (Jim Parsons) and Leonard Hofstadter (Johnny Galecki). She's a struggling waitress; they're brilliant scientists fumbling in relationships. The perfect comedic mix.
"The more, the merrier," as Howard (Simon Helberg) and Raj (Kunal Nayyar) deliver the signature humor that cements this as one of history's top sitcoms. Catch it on Netflix today!
