"Skeptic" is a song by American heavy metal band Slipknot from their fifth studio album, .5: The Gray Chapter.

The song is a tribute piece to late bassist Paul Gray who died from a drug overdose in May 2010.

[3][4] The song was uploaded to their official YouTube channel on the same day as the Japan release of .5: The Gray Chapter on October 17, 2014.

Loudwire stated "Today, we treat our ears to ‘Skeptic.’ Fans will automatically zone in on the track’s chorus: “The world will never see another crazy motherfucker like you / The world will never know another man as amazing as you.” Additional lyrics such as, “You were a gift,” “He was the best of us” and “I will keep your soul alive” point further toward Gray as the man referenced in ‘Skeptic.

[6] Describing the song as "one of the year's most affecting love songs" that takes Slipknot "to surprisingly maudlin heights on the scream-along chorus", the magazine also noted it as "a rare unmasked moment for the enduring septet".
