Just Green Horseradish
Real wasabi is a waxy root that you grind down and serve fresh as a paste to add a sweet and pungent flavor to delicate foods like sushi and tataki. Supermarket wasabi (and probably most of the wasabi you've had throughout your life) is just dyed horseradish. That's why people can't stand the green stuff, horseradish is extremely pungent in comparison to the real deal wasabi.

The US government has an official plan in the event that there is a zombie apocalypse in the country. The program is called CONPLAN 8888 (aka Counter-Zombie Dominance) and was first written in 2011. Now, if they only put that time and effort into solving the poverty crisis, we might be in a better place.
