I don’t know what kind of addictive and mind-altering drug McDonald’s puts in their Japanese Happy Meals.
Maybe it is something like catnip for kids?
Whatever the case, just be glad these kids aren’t showing up at your kid’s next birthday party.

Did you ever get that excited about anything?

Why can’t it be like the good ol’ days?  As far as I know, back in golden times, you could only get addicted to drugs and alcohol.  If you go back farther, I guess it was just alcohol.  But today, people are getting addicted to lots of stuff: food, television, video games, bungee jumping, robbing banks — to name a few.  What has changed within us as human beings that makes us so vulnerable to being addicted to so many things?  Can’t we just go back to the way things were?  Drugs and alcohol?  Maybe just alcohol?  That way, no one gets hurt.  I mean, who has ever been hurt because of alcohol?
