Wanna be the best mom ever?

Help them build a fort.

Then let them read in the fort, sleep in the fort, and generally wreak havoc in the fort.

Wanna be the worst mom ever?

Let the heaviest book known to medical students fall on their heads.

Not that this actually happened (though it's a miracle it didn't). But I could just envision the conversation in the ED....

"So, chief complaint is headache? When was the onset?"

"Well, it was about the time the 25-pound book fell on their heads."

"And what book was that?"

"It was Harrison's."

"Harrison's?! Why didn't you lead with that? We need to get a head CT Stat!"
