From Ross and Rachel to Booth and Brennan, "will they/won't they" couples have become a staple part of our TV diet, with shows often dangling the carrot of love above viewers' heads right up until the very last episode. But CBS' geektastic comedy 'The Big Bang Theory' is way too smart (literally) for that, deciding to forgo the frustration and get right down to the romance after finally hooking up nerdy Leonard (Johnny Galecki) and vivacious Penny (Kaley Cuoco) at the start of season three.

But the course of true love never did run smooth. AOL TV recently stopped by the 'Big Bang Theory' set to get the inside scoop from all five 'Big Bang' cast members, and we think fans will be surprised by what they had to say. Check out our spoilertastic interview after the jump.

During a recent visit to the set of CBS' hit comedy 'The Big Bang Theory,' Simon Helberg, the man who wears Howard Wolowitz's tight pants, gave us an update on the status of the rumored sequel to Joss Whedon's cult web series, 'Dr. Horrible's Sing-Along Blog.'

'Horrible' fans may have recognized Helberg as the villainous (and slightly damp) Moist, henchman to Neil Patrick Harris' Dr. Horrible in the original series, and as far as Helberg knows, he's in line to reappear for the sequel.

(S03E15) I'm pinch-hitting for Kona this week due to technical difficulties at the Gallagher homestead. Not sure if I can be the quote machine she is, but you can always add your favorite quotes from the episode into the comments.

You know, I've never been one to take Sheldon's side a lot of the time. As much as I love the character and how Jim Parsons plays him, the fact that a guy who's such a pill can have four people in his life who like him and tolerate his weird, Aspberger-like selfishness should be enough for me to connect to as a viewer. Most of the time, when Sheldon is wreaking havoc over his friends' lives, I'm usually feeling bad for whoever it is -- usually Leonard -- that's getting the brunt of Sheldon's utter Sheldonness.

But this week, I was on Team Sheldon. Why? Because Leonard knows Sheldon would appreciate a trip to the CERN super collider a whole lot more than Penny would, even if the lure of Penny in a snow bunny outfit is a strong one to resist.
