27-37-37 (don't read this blog or i'll contaminate u)

saw a series of this numbers somewhere and i was wondering what that means.
that reminds me of the fuji film commercial on their film number 36-24-36....
then a friend of mine asked me which part r those 3 numbers represents.
i was like.... up, middle n bottom lor...
this person said, well yeah.. up.. how to measure it?
i was like... around your body lor...
this person continued, yeah.... i've once thought it's around each circle... the circumference of it.... n that's y i don't understand y people can get such a big number....
i can't stop kidding abt it: oh right.. coz u need to multiply by two to get this big number....
u can tell i can do math sometimes too... yay!!!
