The provided article text does not contain the actual body of the story about Will Ferrell — only the page's title, navigation menu items and a "Cover Story: Yard Act" tag were supplied, with no substantive content about the 1995 role in question. As a result, it is not possible to accurately summarise what the article says about the role or why it reportedly left Ferrell with a "guilty conscience."

Based on the title alone, the piece appears to be a Far Out Magazine feature revisiting an early role from 1995 that had a lasting emotional effect on the actor and comedian, but no further details, context, quotes or numbers were included in the text provided. A reliable summary would require the full article content to be supplied.
