Until you have been pushed in and squeezed, I wouldn't say it is funny. It's a fact of life there. During the day, more than 2 million people comes into the Tokyo area. When I was living there, I could let my briefcase go and the darn case wouldn't drop cos there's simply no room to even scratch your butt!.
I'm sure Singapore will one day reach this point when the population reaches more than 7 million people.
The day will come when Singapore has 6 millions poupulation.
