Chewing gum can 'enhance breasts'
"A chewing gum which the makers say can help enhance the size, shape and tone of the breasts has proved to be a big hit in Japan."
"B2Up says its Bust-Up gum, when chewed three or four times a day, can also help improve circulation, reduce stress and fight ageing.
It cites tests carried out by Thailand's Chulalongkorn University which found Pueraria mirifica therapy was able to enhance breast size by 80%."
oh man ... the pranks I could pull on the guys with this stuff.
