Here we go again. This Sesame Street sound bite is being called the new Yanny/Laurel.
In the clip, Grover says, "Yes, yes, that sounds like an excellent idea." But people are hearing, "Yes, yes, that's a fucking excellent idea."
Obviously, Grover isn't swearing. After all, Sesame Street is a kids' show. But, listen to the video and you might just hear his F-bomb for yourself.
