Hackers seized the YouTube page of the “Sesame Street” children’s show Sunday, reprogramming the page with content brought to you by the letter “X.”

You get the idea.

The show page was taken offline, and visitors were greeted with a message from the video website informing them it had been shut down “due to repeated or severe violations of our community guidelines.”

Visitors were greeted with explicit sex videos instead of Muppets.

A message posted on the hacked page claimed two YouTube users were responsible.

One of the pornographic posts was allegedly by someone with the username “Mredxwx” but the YouTube user posted a video denying involvement.

“I did not hack Sesame Street. I am an honest youtuber,” a statement on the 18-second video states.

“I work hard to make quality gameplay videos and most important I respect the community guidelines.”

Sesame Workshop has since released a statement to respond to the hacking. “We apologize for any inconvenience our audience may have experienced today on our Sesame Street YouTube channel,” so the workshop wrote on its official Facebook account.

“Our channel was compromised and we are presently working with YouTube/Google to restore our original content. We always strive to provide age-appropriate content for our viewers and hope to resolve this problem quickly.”

Is it wrong to laugh?
