When someone absentmindedly hums a tune over and over to themselves, much to the annoyance of people around them.
Mrs. Mandrake: (humming Star Wars theme) "Duuh Duuh da da da Duuh Duuh da da da Duuh Duuh dun-dun-dun-duuuuh..."

Mr. Mandrake: "Uh, are you just going to keep idiot humming all night?"

Mrs. Mandrake: "What?... oh the humming! Sorry, I have Star Wars stuck in my head."

Mr. Mandrake: "I know."

...5 minutes later...

Mrs. Mandrake: "Duuh Duuh da da da Duuh Duuh..."
