Noah Kahan jokingly told concertgoers that Congress should require them to wear nappies at his shows, following repeated reports of fans urinating or defecating in the audience. The remarks highlight concerns about concert etiquette and the burden such incidents place on venue staff and other attendees.

The singer first responded online after alleged incidents in Philadelphia and elsewhere, urging fans to use the toilets provided. He later led audiences in a pledge not to soil themselves or leave waste on the floor, before extending the joke during a Washington DC performance by pretending Congress had passed a nappy-wearing law. Kahan has also previously asked fans to stop stealing a street sign referenced in one of his songs.
