Knocked up

Plot Outline:
A young guy finds out he impregnated his one night stand who's way out of his league.

Summary:
Katherine Heigl (Grey's Anatomy) is the main pull of this poster. But the use of colours, fun feel, reference to the hugely popular 40 Year Old Virgin which shares some of this cast, plus the jokey rude tagline, suggest it could be a fun date movie for both sexes.
