The Malibu Bikini Shop (1986)

After inheriting a failing bikini shop, two recent grads decide to make a go of it. One, in the hopes of building it into a successful business, the other, in the hopes of getting to look at lots of women in (and out) of swimsuits. As they try more and more outrageous ways of drumming up business, their antics begin attracting some unwanted attention.
