I never realized this when I played this game as a kid. Hmm. [via]
Anyway, it looks like Hasbro has updated the game a bit and included a bit more variety in characters (although there seems to be more than one version of the game as evidenced in this picture gallery). The one I had as a kid was the one featured in the video above.

Hahahahaha, I remember once when we were still living in Miami, Mun and I played this game so many times in one day that Mun started asking the questions in her sleep.
