Penny : Happy Valentines Day!
Leonard Hofstadter : Flowers and chocolates? You trying to get me out of my panties?
Penny : Don't be surprised if you find five chocolates missing and three gross coconut ones with a bite taken out. Came that way when I bought it.
Leonard Hofstadter : I got you a little something too.
[Gives Penny a jewelry box]
Penny : Oh my. Jewelry.
Penny : Oh, my God. Lakers' tickets!
Leonard Hofstadter : It gets better. Instead of me, you can take someone who will actually enjoy it.
Penny : Aww! You are the best boyfriend ever!
Leonard Hofstadter : Thank you, seriously, please don't make me go.
Penny : Should we take this little party to the bedroom?
Leonard Hofstadter : We don't have to. We have the whole place to ourselves.
Penny : Oh that's true.
Leonard Hofstadter : In fact, if you want we can do it right here on Sheldon's spot.
Penny : That is the least sexy thing anyone's ever said to me.
Leonard Hofstadter : To the bedroom!
Bernadette Rostenkowski : You sure you guys don't want to come with us to Napa. You can probably still get a room.
Penny : No. I think we'll just have a quiet weekend at home.
Leonard Hofstadter : Of course I'm not sure it's a great idea to take Penny where wine comes from. What? It's a joke. Oh, come on. We bust on each other. I wear dorky glasses and you might have a problem. It's all for laughs.
Penny : That would really piss me off if I didn't have a buzz going on.
