“One Tree Hill” has been on the air for eight seasons now (really) despite a mediocre script and average acting. Why might that be? Here’s a novel theory: The producers threw a bunch of smokin’ hot women into one show, dressed them in a minimal amount of clothing and started counting the dollars. It’s that simple, people. The current cast features Sophia Bush, Bethany Joy Galeotti and Lisa Goldstein, all of whom look ridiculously hot in the this week’s episode. But we’d never expect you to actually watch “One Tree Hill,” so we’ve reduced the show down to its five hottest parts. Think of it as David Letterman’s top 10 list with half as many things and four times as many ladies. Roll the tape, Johnny.
