The Vacation Solution - S5-E16
Howard: I'm not signing a pre-nup.
Penny: Alright, Howard Wolowitz, listen up. You sign anything she puts in front of you because you are the luckiest man alive. If you let her go, there is no way you will be able to find anyone else. Speaking on behalf of all women, it is not going to happen, we had a meeting!
The Countdown Reflection - S5-E24
Sheldon: All right, my turn. Howard, Bernadette. DaQH Daj mo...DaQH...
Bernadette: Sheldon! I told you no Klingon.
The Countdown Reflection - S5-E24
Amy: Bernadette, I want to thank you for allowing me to be your maid of honor. I also want you to know that I will be happy to do it again if this marriage craps out.
Suggested correction: Not being able to afford doesn't necessarily mean he doesn't have the money, especially a man like Sheldon. He works with a budget and he sticks to it. In his budget he has a certain amount set aside for rent, anything more than that and he can't afford it alone.
Nonsense. If he was sticking to a "rigid budget" he wouldn't have even thought of lending a hopeless credit risk like Penny a single cent. Instead he throws a huge bankroll at her without even discussing a repayment plan.
Rubbish, I stick to a strict budget but still have the money to lend to close friends. Like Penny is to him.
He might have different budgets for different things. People could get a higher margin because they could be of more use to the scientific mind of Sheldon.
