Snake Eater Syndrome
A weird phenomenon involving the 2004 video game Metal Gear Solid 3: Snake Eater, where seeing a ladder automatically reminds one of the section in the game where Naked Snake has to climb a very tall ladder. This triggers recall of Cynthia Harrell's song Snake Eater, and in many cases verbal mimicry of the song.
Person 1: "oh hey look, a ladder!"
Person 2" "What a thrill..."
