Pre-schoolers may need to let their older siblings watch an upcoming “Sesame Street” episode when the members of One Direction show up to explain the letter U.

“Sesame Street” has not released the full video of the bit, unfortunately. But even a short tidbit is certain to get the tweens and their precocious younger siblings excited about the alphabet, set to the tune of 1D’s hit “What Makes You [or U, in this case] Beautiful.”

Granted, the One Direction boys don’t exactly come up with the most obvious “U” words in this clip — unless you go with “uh” and “udon” (as in the Asian noodles). Who cares, though? They’re cute, and so is the Muppet U. That’s all that really matters.
