Malcolm in the Middle, Season 4

[A furious Hal and Lois are forced to miss Dewey's play by having to pick up an injured Reese and Malcolm from the hospital.]

Lois:
I should've told the doctor to sew furs and tails on you boys because you're animals! Only animals are easier because then I can have you FIXED!

Hal:
For all the good it does, you're grounded again.

Malcolm:
Thanks a lot for getting me grounded on my birthday!

Reese:
Oh boo hoo, I was grounded on my birthday!

Malcolm:
I was just standing up for myself! There is such a thing as justice, you know?!

Reese:
Well, there is such a thing as "Shut up"-!

Lois:
Stop it. Malcolm, do you remember what you did for your birthday last year?

Malcolm:
Nothing. I was grounded then, too.

Lois:
(to Reese) And what about your birthday?

Reese:
You grounded me after I smashed Malcolm's face into the cake.

Lois:
And your birthday before that?

Malcolm:
Pretty much this.

Reese:
(to Malcolm) Wait. When did you push me off the pony?
