Chuck Lorre is simply amazing. He makes every episode of 'The Big Bang Theory' a special one. Here, on Season 10 Episode 13 'The Romance Recalibration', Shamy advice married couple Leonard and Penny how to maintain their relationship.

Leonard and Penny are married since a long time. Penny misses the day when Leonard used to surprise her regularly with his caring and love.

Entertainment Weekly writes that Penny needs some pink wine, mini pizza bagels, and a heartfelt poem from the lyrics of her favorite song. But she sees Leonard sitting on the couch, burping so hard his character dies in the video game he's been playing for hours.

Amy hosted a girls' night at her place. While drinking and eating snacks, she praises his boyfriend, Sheldon for the goal he recently found to take more interest in others' life. He is just like her imaginary boyfriend in college.

Penny complains about Leonard but Amy stops her right away and tells her that not to complain about anyone during girls' night. Leonard and Sheldon have a boys' night across the hall. Sheldon asks Leonard that at their age, why don't they call it man's' night and Leonard reply that they have still spent their entire allowances on comic books.

When Penny returns, Sheldon asks her about the girls' night but she replies in one-word answers which upset him. Leonard warns him no to irritate his wife which upsets Penny. She replies that at least he is asking about her.

Couple escalates into an argument and Penny took Amy to a spa weekend instead of Leonard. Next day, married couple notices Amy and Sheldon share a passionate goodbye kiss. Penny pulls Amy away from Sheldon and they went into the hallway.

Sheldon realizes that Leonard needs to put some effort and they both drive to the spa. But Penny wasn't happy to see him and it annoyed Leonard. They both wants to be back on track but they don't know how to do it.

Sheldon and Amy suggest that they should make a relationship agreement. The Hofstadters recruits Sheldon to draft that. Obviously, it doesn't solve each and every problem, but it surely is effective and creates some compulsory rules.

Some examples as written by Glamour Celebs, Leonard will restrict video gaming in underpants to hours Penny is not home. And if Leonard questions Penny about something that might be bothering her, she's not allowed to say everything is fine if it isn't.

Now that there is an agreement, it will be fun to see whether Leonard and Penny stick to it or not in the future episodes. 'The Big Bang Theory' airs every Thursday at 8 PM E.T. on CBS.
