Overview

In this episode of Lateral, host Tom Scott is joined by comedians Verity Babs and Rosalie Minnett, along with game show enthusiast Bob Haig, to solve a series of curious lateral thinking puzzles. The panel tackles questions about Boston tunnel tiles, 1950s horror movie audience participation, urban exploration tactics, counting systems in South Asian languages, tech support tricks, art theft, and emo hairstyles from the 2000s.

Boston Tunnel Color Coding System

The panel investigates why Boston's O'Neill Tunnel features rows of either blue or brown tiles. After initial speculation about patterns and design choices, they discover the tiles serve a practical purpose for drivers navigating the extensive tunnel system created during Boston's massive Big Dig infrastructure project. The color coding helps both drivers and workers understand their position relative to the city's geography.

  • The O'Neill Tunnel in Boston features rows of tiles that are either blue or brown
  • The Big Dig was one of the most expensive infrastructure projects in US history
  • Blue tiles indicate sections where drivers are underwater, brown tiles indicate underground sections
  • The color system helps drivers track their location by knowing the above-ground geography
" The Big Dig is like one of like the most expansive or costly projects that we we have done in the states "
" Blue tiles on the walls of some of the tunnels mean you're underground. Blue tiles mean you're underwater. "

William Castle's Interactive Horror Cinema

The discussion reveals how a young woman in her twenties participated in a 1959 horror film exactly as the director intended, despite his death in 1977. The answer involves William Castle, the legendary gimmick horror director who pioneered interactive cinema experiences. His film The Tingler featured planted audience members who would scream and faint during screenings, creating an immersive horror experience that modern revival screenings still recreate.

  • William Castle was known as the king of gimmick horror movies in the late 1950s and early 1960s
  • Castle used theatrical gimmicks like vibrating seats, skeleton props flying over audiences, and coward's exits with refunds
  • The Tingler featured planted performers in the audience who would scream and faint as if attacked
  • Modern revival screenings recreate these stunts with live actors
" The Tingler is loose in this theatre, ladies and gentlemen. "
" There should definitely still be a Cowards exit for any film to be like, I just need to get out of Wuthering Heights right now. "
