Fans of rapper Eminem have also noted some similarities in Em's style to that of Lehrer. The style comparison is best evidenced on Em's South Park parody "The Kids" with its piano backing, clever use of syntax and off-beat rhyming, and even references to torturing small animals similar to that of Lehrer's notorious "Poisoning Pigeons In The Park".Heh
