Fat Penguins have to Exercise in Japan
In a Japan zoo, the penguins have to exercise because they are
getting fat. Visitors seems really amused by exercizing
penguins.

Authorities at Asahiyama Zoo are taking the penguins on 500-yard
walks on the snowy grounds twice a day, said zoo spokesman Tetsuo
Yamazaki.
"Just like in humans ... the fat accumulates during the winter
months, and the blood-sugar level rises," Yamazaki explained from
the zoo, 570 miles northwest of Tokyo.
