In the minute-long clip, MacFarlane says he's been asked to host the Oscars, and his dad responds by offering him some "barely used" bathing suits.
"I've invited you here today to tell you I'm hosting the Oscars," MacFarlane says. "This should be huge news to you."
"Of course, it's wonderful news," his father replies. "But also the fact that you're getting almost brand-new bathing suits is also good news."
When MacFarlane seems unappreciative, dad snatches back the swimsuits and says, "I'm going to give these to Billy Crystal."
Crystal hosted the last Oscar show. Other recent hosts include Steve Martin and Alec Baldwin, James Franco and Anne Hathaway, Hugh Jackman, Jon Stewart and Ellen DeGeneres.
