What IS THAT?

"Oh hi, Daphne! How---AAAAAHHHH! THERE'S SOMETHING ON YOUR HEAD!!!"
"AHHHHH!!!!! WHAT!? WHERE!?            Oh. You mean my hat?"
"That's a hat?"
"Naturally."
"Um... May I ask who gave it to you?"
"Found....  Why?"
"Figures it was her, doesn't it?"
"What do you mean?"
"Oh, nothing...She likes a joke, that one, doesn't she?"
"Jokes? Man, Lost, you always were one for changing the subject! We were talking about my hat!"
"I WAS talking about your hat!"
