Nothing is a secret in TV nowadays. With the internet, spoilers, Twitter – you name it – surprises are pretty damn hard to come by. Especially for us UK dwellers hooked on slick American exports. So, with that in mind, if you DON'T want to know about this super exciting Big Bang Theory guest star, stop reading NOW.
But if you do... well, creator Chuck Lorre has an exciting episode in store for you.
Tonight's instalment sees Sheldon, Leonard, Howard, Raj and Penny joined by Billy Bob Thornton. The Oscar-winning Fargo star created a massive bang over in the States in October by appearing in The Misinterpretation Agitation as a sad urologist to the stars.
His character, Dr Oliver Lorvis, develops a crush on Penny after she visits his clinic but it's a case of unrequited love. Turning up on her doorstep with flowers and the hopes of "initiating a romantic relationship", his endeavours are soon halted by her fiancé Leonard.
But the rest of the gang take pity on poor Oliver, inviting him in for dinner and befriending him. Well, wouldn't you? It's Billy Bob Thornton.
Thornton first hinted of his desire to appear on the hit US comedy back in July, announcing his desire to "want to be a guy who steals Penny away." While he doesn't exactly succeed, his efforts are certainly entertaining. Take a look below...
