While in Dublin promoting their latest film Trainwreck, comedian Amy Schumer and director Judd Apatow led revelers at Grogans pub in a rousing sing-a-long to “The Auld Triangle” with Irish songwriter Glen Hansard (known for starring in the film Once) on Friday .

They sidled up next to a bride and groom, J.P. Swaine and Eithne McAdam, who were sharing a pint with their wedding party.

The comedian has just been full of surprises this year, between photobombing a couple’s engagement photo and tipping a waiter $500 on a $49 bill. But nothing can top the time she pranked Kanye West and Kim Kardashian by pretending to fall in front of them on the red carpet at the TIME 100 gala:
