Cartman Residence- Morning. Eric and Heidi were sleeping peacefully in their bed; that peace was cut short when the sound of little footsteps came running down the hall, getting louder with each step. Suddenly, the door flew wide open and a girl with brown hair and wearing crimson pyjamas jumped on top of the bed.
Lindsay: Morning Mommy. Morning Daddy! Get up!
Cartman (Yawn): Morning, sweetie. Is there ever a morning where you aren't so energetic?
Lindsay: Nope. (Giggles and runs off)
Heidi wakes up.
Heidi: She's been more excited than normal Eric.
Suddenly, she felt like she was going to be sick. She jumped out of bed (not literally, of course) and ran for the bathroom. She is heard throwing up in the toilet. She flushed the toilet, washed out her mouth and got back into bed with her no-longer fat husband.
Heidi: I doubt I'll ever forgive you for knocking me up that one night after graduation. Because of you, my studies got delayed after I had Lindsay. And now, look at this. (She lifts up her shirt, exposing her bump to Eric) This was all your fault.
Cartman: On the bright side Heidi. At least we'll have another bundle of joy to accompany Lindsay.
Lindsay (From the hall): I want my baby sibling now!
Cartman: In a few months sweetie! (To his wife) Wanna go for an ultrasound today?
Heidi: Sure.
They kiss and get out of bed.
Later that day- Heidi is having her ultrasound. The doctor looks at the screen as he scans Heidi's swollen stomach with a probe.
Doctor: Would you like to know the gender of your second baby?
Cartman/Heidi: Yes please!
Doctor: Well, we've confirmed that it's a boy.
Later at home-
Cartman: Lindsay, we got news.
Lindsay: Is the baby here?
Heidi: No. In a few months, you're going to have a baby brother.
Lindsay's face lit up even more.
Lindsay: Yay!
