"That Green Gentleman (Things Have Changed)" (often shortened to "That Green Gentleman") is a single by American rock band Panic! at the Disco, from their second studio album Pretty. Odd. The song was the second song written by the band after they decided to scrap an album's worth of material, but was not played with "When the Day Met the Night" and "Nine in the Afternoon" at the various festivals Panic performed at during the summer of 2007.

The title of the album was already decided before the line, "Things are shaping up to be pretty odd" was written.^[2]

The song was performed (as well as "She's a Handsome Woman", and "Mad as Rabbits") on every date of the European tour prior to the album's release.

This single was also performed during the June 12, 2008, episode of FNMTV,^{[citation needed]} hosted by Fall Out Boy's Pete Wentz.
