pentatonix sesame street Pentatonix teaches you about counting on 'Sesame Street'Internet, your favorite a cappella group has teamed up with your favorite pop culture-friendly children’s show for an excellent educational video. “The Sing-Off” Season 3 winners Pentatonix recently visited “Sesame Street,” and the show has posted the soon-to-air video of their appearance.

Get ready for a cute little ditty about counting that will be stuck in your head all day. Also, be prepared for your semi-regular reminder that beatboxer Kevin Olusola also has an amazing singing voice that we unfortunately don’t hear very much due to his mind-blowing beatboxing skills.

If the above video wasn’t enough, check out this cute “C is for Cookie” and “Rubber Ducky” mashup they recorded in their dressing room before their appearance — you might recognize a certain blue Cookie Monster who sneaks in to assist with the video.

Pentatonix’s episode of “Sesame Street” airs on Feb. 7.
