After the beloved character’s X account was hacked, Jon Stewart decided to have some fun with a look-alike puppet of Elmo on the “The Daily Show ” on Monday. The talk show host reminded the audience with a photo that he had worked with the famed muppet years ago and said he was “shocked” by the tweets.

"Elmo's X account was briefly compromised yesterday by an unknown hacker who posted disgusting messages, including antisemitic and racist posts. The account has since been secured," a spokesperson for Sesame Workshop, the nonprofit educational organization behind Sesame Street, said in a statement to ABC News on Monday.

Sesame Workshop said the X account for its beloved fuzzy, red monster Elmo was compromised by an "unknown hacker" who made antisemitic and racist posts on Sunday.
