A Venomous Sibling Relationship

(A friend gets a call from his brother. After talking a little:)

Friend: “Oh, did you know that Mom got bit by a rattlesnake?”

Brother: “No, I didn’t! Is she all right?”

Friend: “Yeah, they kept her in the hospital overnight, but it was a dry bite, and she’s okay.”

(Dry bites are when the snake doesn’t inject any venom. They are surprisingly common, as the snake doesn’t want to waste the venom. [Brother] thinks about it a minute and then calls their sister.)

Brother: “Hey, sis, did you know Mom got bit by a rattlesnake?”

Sister: *screams* “NO, I DIDN’T! Is the snake okay?”
