The A.V. Club by Scott Tobias

There certainly are labored stretches and groan-inducing gags, but between the suggestive names (Melvin Jerkovski, Bootsie Goodhead, Principal Stuckoff), the deliberately broad characterizations (the Richie Rich type carries his tennis racket everywhere he goes), and the air of unbridled permissiveness, the film feels about as wholesome as a T&A-fest could possibly be. It makes a strong case for being the definitive work of a disreputable subgenre.

And because it is less bound by formula -- less stupid, if that can be comprehended -- than Porky's, Screwballs is funnier. That is not saying much, but Screwballs was not conceived as a film for scholarly inquiry. If you like naked women posing as high-school cheerleaders, your moment has arrived.

Variety

A poor man's "Porky's". This compendium of horny high school jokes set in 1965 is full of youthful exuberance and proves utterly painless to watch, but it is so close in premise and tone to its model that negative comparisons can't help but be drawn.

Trying to jump on the PORKY'S bandwagon, the makers of SCREWBALLS came up with another bad, teen sex comedy. The girls are given degrading names, the boys have only one thing on their minds, and the producers obviously have no sense of social or artistic responsibility.

Time Out

However one rates the bosom as an erogenous zone, it takes the talents of a Russ Meyer to make it interesting for eighty minutes. Watching the unflagging, unfunny efforts of five callow youths to see the homecoming queen's breasts, one only wonders if ever in the field of endeavour so much has been done by so many for just two.

Screwballs establishes that - in the absence of talent - teen-age prurience, old Thunderbirds, rock music and hula hoops do not add up to entertainment.

Chicago Sun-Times by Roger Ebert

Screwballs opens outside the local hot dog stand, where a giant inflatable hot dog is swinging back and forth like a pendulum, gently nudging the backsides of two teenage girls. From such beginnings I suppose we should not anticipate a masterpiece, but the opening shot is the high point of this dumb movie.
