Apparently, spam and egg sandwich ("supamu sando") is quite popular in Japan.
A couple months ago, Bunk sent me this advertisement for a Spam Sandwich sold at Freshness Burger, a very popular fast food chain in Japan and South Korea: For about $4 U.S., you can have a big hunk of spam, lettuce, tomato, and an over-easy egg. So yummy, you’ll go “Boing” when you eat it.
More seriously, there is a Western fascination for asian Cultures, especially for Japan, where they are "modern" like us (with cars and fast food and high rise buildings) and yet they have really different outlook and mentality from us.
Also, Japanese people have a fascination with Western "culture" especially american culture. It goes both ways.
America america, too much coffee.
I'm quite sure that Japanese parody Americans in humor and media as well -- more power to them! There certainly are stereotypes regarding Americans, and they are free to pick at it with funny news items and bits from US culture. So roosen up and don't be so sensitive!
