Whoopee!

Daisy Duck: So you can't sell brushes because nobody understands a word you say? Donald Duck: Yes. Daisy Duck: Don't worry, Donald. Don't give up! I have faith in you. Go out and try again.
[she kisses him; Donald is filled with renewed energy] Donald Duck: Whoopee!
[he bounces out of the house, brush case in hand; Daisy watches him leave] Daisy Duck: Good luck, darling! Donald Duck: Good-bye, sweetheart!
