"Another round," Penny said to the bartender at the cheesecake factory bar. He poured two more shots for Penny and Sheldon. They drunk it then Penny said, "Leonard took your meemaw's letters and my teddybear home, so they are safe. Now what were we talking about before we were talking about that?"

"I don't remember," Sheldon laughed at his remark, "But I'm changing the subject to...Beverly."

Penny poked her tongue out at the mention of the back stabber. Sheldon continued "Do you know what sad about my relationship with you?"

"No, what?" Penny asked, curious now.

"She says we're in a love/hate formulated relationship. The two of us are polar opposites and love and hate are polar opposite feelings. Love and hate are intimately linked within the human brain, according to a study that has discovered the biological basis for the two most intense emotions.

Scientists studying the physical nature of hate have found that some of the nervous circuits in the brain responsible for it are the same as those that are used during the feeling of romantic love – although love and hate appear to be polar opposites. It can be argued that, due to the fact that the subjects, us, are friends despite issues we have, a love hate relationship represents a stronger bond than a simple love relationship does," Sheldon took a bite at a bread stick.

Penny narrowed her eyes in confusion, "Ok, whatever," then Penny mumbled, "Didn't understand a thing you said."

Penny ordered a Cuba Libre for Sheldon and a Grasshopper for herself. Halfway through their drinks, Sheldon admitted, "I enjoyed your performance in Avenue Q Penny. The only reason I said those things to you a while ago, was because I've seen it hundreds of times. My aunt loves it and so she taught me the songs on the piano and made me see it every time it came around."

"Really?" Penny asked, "What was your favourite song?"

Sheldon took another sip of his drink, "Your favourite is my favourite."

"My favourite is the part I had played. I was Christmas Eve and the song was The more you Ruv someone."

"Then come on Penny," Sheldon grabbed Penny's hand, with his drink in the other hand.

"What are we doing Sheldon?" Penny asked as Sheldon lead her to the stage with the keyboard.

"We're doing the song. I know how to play it and you know how to sing it. It's a duet isn't it?"

"Yes but, but, but," Penny didn't know how to argue.

Sheldon sat down and the keyboard, "Come on, your voice isn't that bad."

Penny rolled her eyes, she wasn't sure if she should take that as an insult or compliment, "Fine, but afterwards I'm going to kill you."

"You should've done that hours ago," Sheldon smiled and checked if the keyboard was on.

Penny turned on Sheldon's microphone then turned on her hers, which was on a mike stand next to the keyboard.

Peple at their tables turned to watch the stage. Penny was nervous. Stupid drunk Sheldon, Penny thought.

Penny sung the first verse with the piano quietly playing in the background like the song starts;

"The more you love someone,
The more you want to kill him.
The more you love someone,
The more he make you cry,"

"Though you are try
For making peace
With them and loving,"My voice sounds high, Penny thought, I'm singing terribly, Damn Sheldon!

"That's why you love so strong
you like to make him"Penny turned and faced Sheldon "die!"

But the anger faded away instantly as Penny looked at Sheldon's smiling face. That was the moment Penny fell for Sheldon. Who knows why, Penny thought. It could be the liquor talking, but all she knows right now is that she's in love.

Penny sung the next verse deeper and with meaning in her words;

"The more you love someone,
The more he make you crazy.
The more you love someone,
The more you wishing him dead!"

"Sometime you look at him
and only see a head on a stick,"

Sheldon giggled, "Those aren't the lyrics Penny," still playing the song.

Penny smiled, "I know that, but you're not fat and lazy."

Sheldon looked confused, "What are you implying"

"Shut up," Penny said. She had to skip the next two lines to keep up with the piano, it was up to the duet;

"Love,"

"Love," continued Sheldon.

"And hate,"

"And hate,"

"They like two brothers,"

"Brothers,"

"Who go on a date," Penny sung.

Sheldon giggled again, "That's the funniest part of the play!"

Penny's voice got stronger;

"Where one of them goes,
Other one follows
You inviting love
He also bringing sorrows"

"Your singing great Penny," Sheldon smiled.

Sheldon played faster, the song was near to the climax;

"The more you love someone,
The more you want to kill him.
Loving and killing
fit like hand in glove!"

Here came the climax, Penny was putting her heart and soul into the moment;

"So if there someone
You are wanting so
To kill him."

Sheldon slowed the piano down, and Penny's voice went softer;

"You go and find him."

Penny took the microphone off the stand;

"And you get him."

She walked towards the piano and shook her head;

"And you no kill him."

Penny slowly sat next to Sheldon on the piano seat;

"Cause chances good,"

Then they both sung the last line, as Sheldon concluded to song;

"He is your loooooove."

Penny closed her eyes, pouted her lips and waited for Sheldon to kiss her. But Sheldon just said, "Great song," then walked off the stage with his almost empty drink.

When she opened her eyes, Sheldon was back at the bar. Obviously he didn't feel the moment she had felt.

"Crap," Penny said, "I'm in love with a man who doesn't have a 'deal',"
