Chiefs fans can't stay awake for their season-opening win

Some Texans fans decided to leave early when the Chiefs opened up their late lead.

These Chiefs fans stuck around -- and caught a little shut-eye in the process.

Game-napping is a controversial choice. These guys made the trip to a visiting stadium, but fell asleep. Where does that lay on the spectrum of fan etiquette?

One thing's certain -- they saved themselves some stress. The Texans closed the gap on Kansas City in the fourth quarter, but couldn't complete a comeback.

These two are none the wiser. They woke up as winners -- and that's the best feeling there is.
