The real-life relationships of The Big Bang Theory cast

The Big Bang Theory first premiered on CBS September 24, 2007. The sitcom about a group of science geek friends was a hit from the very first episode, and made nerds (and non-nerds alike) fall in love with the adorable personalities of the lead characters.

Geeks everywhere cheered when they saw that at last socially-awkward geniuses got the beautiful girl on television, instead of rejection. Throughout the last 10 seasons of The Big Bang Theory, many on-screen (and off-screen) relationships developed. One of the most famous being Leonard (an experimental physicist) and his blonde bombshell of a neighbor/aspiring actress Penny. When the two first met, it seemed like someone like Leonard, who was not nearly as tall, hunky or muscly as Penny’s previous boyfriends, would ever go for someone like him. In a delightful turn of events, the two form an incredible relationship (on and off) and eventually get married!
