The Internet can't decide if Grover is throwing the F-bomb or not

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.
