Stray Kids sang Christmas carols for fans during a recent V Live broadcast.

Bandmates Seungmin, Bang Chan, Felix and I.N started singing “Joy to the World” during the livestream Sunday, before soon forgetting the lyrics and humming the song instead.

They hummed “Silent Night” before briefly singing another carol, “Rudolph the Red Nosed Reindeer.”

They later opted for a more contemporary tune -- Wham!’s “Last Christmas.”

When viewers asked Stray Kids about their day, they laughed as the day had just begun where they were.

In an interesting turn of events, the bandmates began showing off how flexible they are.

I.N stood up in the studio and struck various poses while stretching.

His moves appeared to have left a strong impression on the rest of the group, with other bandmates praising how strong I.N’s legs are.
