Internet Wondering "Did Grover Drop The F-Bomb?"

I mean, nooooo "Sesame Street" would never allow something like this to happen but it isn't stopping the Internet from asking if Grover saying “Yes, yes, that’s a f**king excellent idea” ORRRR “Yes, yes, that sounds like an excellent idea.” 

Seriously, I've listened to this like 50 times and I can hear it both ways depending on what I am expecting to hear (WHAT DOES IT ALL MEAN?!)
