Rating: O (R)

A carefree salesman (Seann William Scott) and his caustic partner (Paul Rudd), sentenced to community service, ineptly mentor a tough-talking fifth-grader (Bobb’e J. Thompson) and a socially awkward teen (Christopher Mintz-Plasse). Despite a redemptive story line and some solid performances, director and co-writer David Wain’s buddy comedy — which also features Jane Lynch as the mentoring program’s manic director — goes awry mining laughs from casual sex and an expletive-spouting, sexually precocious child. Strong sexual content, including frontal-male, upper-female and rear nudity and nongraphic, nonmarital sexual activity; cohabitation; much sexual humor; pervasive rough and crude language; the occasional use of profanity; and drug use. The USCCB Office for Film & Broadcasting classification is O — morally offensive. The Motion Picture Association of America rating is R — restricted. Under 17 requires accompanying parent or adult guardian.
