For a band called One Direction, they sure have been traveling all over the place the past few days.
Before they released their fourth studio album, Four, Monday morning, the former X-Factor contestants paid a visit to Sesame Street where they delivered an important message to their youngest fans.
In a parody to their hit song "What Makes You Beautiful," the guys sang about the importance of being useful and most importantly, the letter "u."
"I love you, do you know you're so useful," One Direction sings when explaining "u" in the alphabet. "That's what makes you so useful."
Pretty clever, right?
