Why Are They Cool? Okay, so their hair is a little oily, they're still in school and they have a disturbing penchant for breaking into song at every possible moment.
But they're swaggering, leather clad dudes who step up when called upon and know how to handle a street race or two.
And considering that they've got a chattering, cooing gang of women - The Pink Ladies - watching their every move, it's not hard to see why they enjoy life.
Such is the power of their appeal that Danny even manages to convince the school's new arrival, virginal, terrified Sandy (Olivia Newton-John) to become a jumpsuit-clad vixen.
