Star Trek The Original Series scene. We're in a CORRIDOR! A room door is open, and we see two crewmen spilling out into the hallway in red and blue uniforms. They are otherwise indecipherable tho because they are entirely enveloped in a big cloud of smoke. It's pouring out all around them and into the hallway area, like there's a Phish concert in there. Closed caption reads, "[COUGHING]"
