This episode was aired with a 'parental discretion advised' warning at the beginning, the first episode to do so.
Clark "explains" to Chloe that he can hear so well because he missed too many Linkin Park concerts. Linkin Park is an American rock band that formed in 1996 and their former lead singer, Chester Bennington is shown to scream during his songs, which would cause anyone who attends their concerts to have their hearing shot afterward.
