Frank's (Steve Carell) explanation to Olive at the dinner table for why he attempted suicide went from a somber moment to a funny one because of her reaction.
FROM THE SCRIPT:
Olive:
"Why were you unhappy?"
Frank glances at Richard -- deadpan victorious -- and continues.
Frank:
"Well, there were a lot of reasons. Mainly, though, I fell in love with someone who didn't love me back..."
Olive:
"Who?"
Frank:
"One of my grad students. I was very much in love with him."
Olive:
"Him?? It was a boy? You fell in love with a boy?"
Frank:
"Yes. I did. Very much so."
This is new to Olive. She thinks it over.
Olive:
"That's silly."
Frank:
"You're right. It was very, very silly."
Grandpa:
"There's another word for it."
Richard:
"Dad..."
