While four-year-old Nolan Moore sat in the great ape enclosure of the Bio Parco zoo in Rome, Italy, with mom Angela Tomarelli, he tried to play peek-a-boo with a chimp. Despite being disinterested in the game, as soon as the four-year-old pressed his lips to the glass, the ape puckered up too. Each time Nolan planted a kiss on the window, the loving chimpanzee returned the favor, with the boy's mom Angela saying “she thinks you’re her boyfriend now.”
