PLL episode: Season 1, Episode 10
Twin Peaks episode: Pilot

Sure, it's a bit of stretch since PLL's Toby was basically a shut-in Boo Radley-type before he joined rejoined civilization, and Bobby Briggs was always the pretty popular one, but they both start out as the lead murder suspects, and have hair fit for a Tiger Beat poster. While it was believed that Toby was out to get Ali for blackmailing him into taking the blame for blinding his step-sister, Bobby's motive was allegedly his jealously over his ex-girlfriend Laura's affair with another man.
