"Thank You" is the debut single by American pop duo MKTO, composed of Malcolm David Kelley and Tony Oller.

The song was written by Kelley, Oller, Evan "Kidd" Bogart, Emanuel Kiriakou, and Andrew Goldstein.

Malcolm David Kelley and Tony Oller met in the 2010 while filming the television series Gigantic, in which their characters were portrayed as best friends.

[2] Apart from filming Gigantic, the two posted cover versions of songs in YouTube, which caught the attention of Evan "Kidd" Bogart and Emanuel Kiriakou and led to them being signed to Columbia Records in 2012.

The song's accompanying music video was filmed by Chris Marrs Piliero and was released on January 4, 2013, on their Vevo account.

It features an appearance by Harold Perrineau who plays the father of Kelley's character on the television series Lost.

Malcolm, Tony and the students start spraying graffiti and handing balloons to politicians that cause the string to tie around their wrist and sprung in the air.
