Going insane!!!!!

Do you have kids who just repeat the same thing over, and over, and over, and over, and over, and over?
Drew and Louisa could literally spend an entire day repeating the same phrase over and over again. They see something on tv, or hear something on the radio and that's all I hear for the rest of the day.
I'm at my wits end here! Louisa has been singing one line from a Carrie Underwood song the WHOLE ENTIRE DAY! And I only wish I were exaggerating. It goes, "I haven't done this in awhile, and I don't know what to say..." and it's from the song Don't Forget to Remeber Me. She's a total drama queen, too. So each time she sings it she has to put extra emphasis, extra verbrato, extra Umph! into it. She forte's and piano's in different parts each time. Ok, she just did it again, she started out strong with excellent forte..... then dropped to a sweet little piano!
AAAHHHHHHHH!!!!!!!!!!!!! I want to scream my head off right now! VERY FORTE!
Then she starts quoting a line from the tv show The Suite Life of Zach and Cody on the Disney Channel. "Give me death, or give me chocolate!.... Is there a third option?" It was very funny the first time she said it! Now she's said it over 100 times.
Ok, she just did the Carrie Underwood thing again. Now she's talking the line, but talking very fast.
Now she's singing it scat!
There's opera....
Is there an end to this??!!!! I've yelled at her a few times today, but it doesn't work.
There's scat again....
I could not even make this up if I tried!

**Louisa just read this and I've been corrected. It's "Give me chocolate or give me death...". Because of course, according to her, it doesn't sound right the other way!
