Wrong kid died!

Dewey Cox:

What happened? Pa Cox:
I'll tell you what happened. We were readying for bed when your song comes on the radio. [the scene switches to the Cox's house with "Walk Hard" playing on the radio] Ma Cox:
It's Dewey! Your son is talented. You should be proud. Pa Cox:
Well, I must admit, it is kind of... catchy. Ma Cox:
Dance with me Pa. [the two begin dancing] Pa Cox:
It does make you kind of want to move, doesn't it? Ma Cox:
It sure does. Pa Cox:
Maybe I have been kind of hard on little Dewey. Ma Cox:
Maybe you have. [Pa twists Ma, accidentally causing her to lose her balance and fall out the window] Pa Cox:
You alright, ma? Ma Cox:
I'm alright! [the radio falls out of the window and hits Ma in the head, killing her] Dewey Cox:
[starting to cry]
She lost her balance... and fell out the window... and then the radio crushed her head? Pa Cox:
While she was dancing to your song. I thought you should know what your music does. It kills people. You made her happy, and it killed her. If Nate was alive this never would've happened. [Pa begins to leave. As he turns the hall, he comes back around] Pa Cox:
