The Washington Post reports that hundreds of climate change protesters swarmed the field during the annual Harvard-Yale football game this past Saturday and chanted, "OK Boomer!"

According to the report, both schools have long-running campaigns to stop investing endowment money in fossil fuels and forgive Puerto Rican debt.  Protesters sat at the 50 yard line and delayed the action for nearly an hour.  Police made arrests and summonses for disorderly conduct.

One of the signs said, "This is an emergency."
