Carnegie Musuem of Natural History. Saturday Afternoon. Boy Scout Day.
A middle-aged couple finishes walking their kids to a secluded basement classroom:

Man: [pulls on wife’s arm, indicating a closet] Come on, baby, you wanna?
Wife: [slaps him on the arm] Ted!
Man: I’ll do you right here.
[Wife laughs and shakes her head. She grabs his hand and they walk into the classroom together.]
