"Do You Know? (The Ping Pong Song)" is a song by Spanish singer Enrique Iglesias. It was released in 2007 as the first single from his eighth studio album, Insomniac and takes the latter part of its English name from the sound of a ping pong[1] ball bouncing that is employed as a percussion track throughout the song. The song's Spanish version is entitled "Dímelo" and was released to Latin radio, becoming Iglesias' 17th number one song on the US Billboard Hot Latin Songs.
