t's On (Dr. Dre) 187um Killa is the second EP released by American rapper Eazy-E and the last project to be released during his lifetime. It was released on October 19, 1993 via Relativity Records and Eazy-E's Ruthless Records, as a response to Dr. Dre's debut solo album The Chronic, which repeatedly attacks Eazy.To follow up his 1992 EP 5150: Home 4 tha Sick, Eazy-E had planned a double album named Temporary Insanity. Yet to exploit Dre's spotlight and his May 1993 single"**** wit Dre Day", which mainly disses him, Eazy changed plans. On this EP, shots at Dre are absent from only three tracks:"Gimmie That Nutt","Any Last Werdz", and"Boyz-N-the-Hood (G-Mix)". The lead single,"Real Muthaphuckkin G's"—which, alike"Any Last Werdz", carried a music video—became Eazy's most successful single.
