Quote from Moira in Happy Ending
Alexis: [loud cough] David: [wakes up, gasps] What happened? Who died? Johnny: Who died? David: Did Patrick die? Alexis: No, Patrick didn't die, David. David: Then why did you startle me awake like this? My mind went straight to some kind of unthinkable tragedy. Like something really, really bad happened. Johnny: Oh. Imagine. Moira: Well, the day did have a slight singultus.
