Sheldon: What would you like me to say?
Leonard: How about congratulating us?
Sheldon: Are congratulations even in order? I didn't think Penny wanted children.
Leonard: Well, she didn't, now she does. And just so you know, we weren't gonna tell anybody so we wouldn't upstage your big day.
Sheldon: Oh, please, you couldn't upstage us. We won a Nobel Prize. Any idiot can have a baby.
Howard: Hey. What's going on?
Sheldon: Case in point.
