Some people are on a roller coaster ride. Some of them are screaming.
One woman in front is very calm.
Why is she so calm?
I guess this explains last night.

A joke about people falling asleep before sex; being "too tired" is a common trope, especially among married couples. A roller coaster is a very exciting activity for most people, and yet the woman is sleeping on it. The man notices this, and realizes that this woman falls asleep commonly during activities that many people find exciting, like sex, which must have happened to them last night.
