Koko is the primate famously known for having learned sign language and for being able to understand some English.
Recently, RHCP’s bassist Flea was offered the chance to meet Koko, so the rocker took along one of his bass guitars to show her.
Prepare for your heart to melt.
Koko & Flea are practicing. Your excuse is invalid.
