Watch: Jack Antonoff sings ‘I Love Trash’ on ‘Sesame Street’ with Oscar the Grouch

Apparently Jack Antonoff REALLY loves trash

Jack Antonoff made a special appearance on Sesame Street over the weekend, where he sang “I Love Trash” with garbage puppet Oscar the Grouch.

In the clip, Antonoff joined Oscar the Grouch and his trash-loving friends for a musical-style number, until he eventually transformed into a garbage-covered character himself. “I have here some newspaper thirteen months old/ I’ve wrapped fish inside it, it’s smelly and cold,” Antonoff sings as he buries his nose into a fake old fish.
