Urban legend
Urban legend states that urine works well against jellyfish stings. This scenario has appeared many times in popular culture including in the "Friends" episode "The One With the Jellyfish", an early episode of "Survivor", as well as the films "The Real Cancun" (2003), "The Heartbreak Kid" (2007) and "The Paperboy" (2012). However, at best it is ineffective, and in some cases this treatment may make the injury worse.
