Watch Adele Sing "Hello" With Jimmy Fallon, The Roots, Some Classroom Instruments And A Flip Phone

Here's your daily dose of joy.

Adele's ceaseless promotional campaign has led her to The Tonight Show, where she gamely performed heartbreak anthem "Hello" while Jimmy Fallon and The Roots accompanied her on classroom instruments.

She even whips out a toy flip-phone halfway through, for old times' sake.

This might be the only time you smile while listening to her howl, "Hello from the other side."

In other news, Adele's 25, as expected, has gone on to claim the title of biggest ever debut for a CD in America. The previous record holders *NSYNC graciously handed over the crown.
