In 2015, the internet was buzzing about the optical illusion of the blue or gold dress – some people clearly saw a blue dress, while others saw gold.

This past year, many people were confused about an audio recording circulating online of a robotic voice saying either, “Yanny or Laurel”. Today, it’s whether Grover the blue Sesame Street character said the ‘F’ word on television.

One Reddit user posted the clip which has sparked a debate on social media as to whether the children’s television character actually included a swear word in his sentence.

Some users have heard:

“Yes, yes, that sounds like an excellent idea!”

while others hear the expletive included in the phrase, “Yes, yes, that’s a f*****g excellent idea!”

Take a listen for yourself and let us know what you hear: 

May have just found next “Yanni or Laurel” soundbite thanks to my daughter’s obsession with Elmo.
