A pregnant woman hobbles painfully into the hospital with one hand on her back.
The nurse rushes over to her and asks her what’s wrong, but the woman just shouts, “Shouldn’t! Wouldn’t! Didn’t!”
The nurse shakes her head and says, “Sorry, I don’t understand!”
The woman screams, “Can’t! Won’t! Don’t!”
The nurse is really confused and turns to a doctor who says, “Admit her immediately!! She’s having contractions!”
Explanation: The humor comes from the clever wordplay on “contractions”—both the grammatical kind (shortened words like shouldn’t, wouldn’t, didn’t) and the labor pains a woman experiences before giving birth.
