This is our youth, ladies and gentlemen: A reader sent us this video taken on New Year's Day at the West 72nd Street 1/2/3 station, explaining,"This kid went to the side with the HEET because the side with the regular turnstiles wouldn't take credit/debit cards. Instead of going back to the side with the regular turnstiles so he could jump, he decided to climb the HEET and jump."
Other names for the HEET—the high entrance/exit turnstile—are the babyback ribs of death, meat grinder, and iron maiden.
