Cobain or Kobe?

Listen up, nimrod. The joke is about Kurt Cobain and Kobe Bryant. Cobain, the lead singer of Nirvana, died by suicide, which was his "last shot." Kobe Bryant, the famous basketball player, is known for making many shots in his career. The joke plays on the double meaning of "last shot," contrasting Cobain's death with Kobe's successful basketball career. You probably think the earth is flat, huh?
