Friday is brought to you by the letter 'A': For Zac Efron's adorable appearance on Sesame Street!

The hunky 24-year-old Paperboy actor is palling around with a new Hollywood BFF -- Elmo -- and teaching everyone's favorite red guy a bit about patience on the PBS Kids series' Friday episode.

As Elmo urges the actor to shoot hoops with him, Efron calms the muppet down by teaching him how to be patient. "The word 'patience' means to wait in a calm way," Efron tells viewers, and his new furry friend, in the clip above. "Elmo really wants to play basketball, but he's waiting in a calm way -- he's showing patience."

Later, after Efron gets his lesson across, he heads to the court to play basketball with Elmo. "I'm so excited, Mr. Zac!" Elmo enthuses.
