Maybe it’s the way you’re dressed is a quote from the cartoon television series SpongeBob SquarePants, said by Patrick Star.
The quote is the centerpiece of the online conspiracy, that the voice of Sans from Undertale is actually sampled from the titular phrase, taken from the word “maybe”.
The phrase was first heard in the SpongeBob SquarePants episode, titled Something Smells, which was first aired in the United States on October 26th, 2000.
Undertale was released on September 15th, 2015.
Theories, which stated that the voice of Sans in the game is sampled from Patrick’s phrase “maybe it’s the way you’re dressed” started emerging in July, 2019, predominantly on YouTube.
The topic became a popular one, with several users posting several comparisons on YouTube.
On September 1st, 2019, the Souncloud channel of “Undertale OST: Recreated” uploaded a short clip of editing Patrick’s voice into the voice of Sans in the game.
This revelation resulted with a large number of discussions on sites like Twitter and Reddit.
