House, Season 1

Jill:
My joints have been feeling all loose, and lately I've been feeling sick a lot. Maybe I'm over training; I'm doin' the marathon, like, ten miles a day, but I can't seem to lose any weight.

Dr. House:
[while using an ultrasound] Lift up your arms.

Dr. House:
You have a parasite.

Jill:
Like a tapeworm or something?

Dr. House:
Lie back and lift up your sweater.

Dr. House:
You can put your arms down.

Jill:
Can you do anything about it?

Dr. House:
Only for about a month or so. After that it becomes illegal to remove, except in a couple of states.

Jill:
Illegal?

Dr. House:
Don't worry. Many women learn to embrace this parasite. They name it, dress it up in tiny clothes, arrange playdates with other parasites...

Jill:
Playdates?

Dr. House:
[shows the fetus to her] It has your eyes.
