"MakeDamnSure" (originally titled "You're So Cool") is a song by American rock band Taking Back Sunday.

[6] It has experienced much more success than the band's other singles on the Billboard Hot 100 and Alternative Songs chart.

[7] The music video for the song "MakeDamnSure" (directed by Marc Klasfeld) switches between scenes of the band playing in a wind tunnel and scenes of violence and destruction (such as a car crashing from a cliff, or bombs exploding in a village).

The wind in the tunnel gradually increases, and when the loud chorus part repeats for the last time, it almost blows them away.

The video ends as Adam Lazzara, who's viewed singing in profile, slowly turns into a boy, who blows on the microphone, which has turned into a dandelion, whose seeds blow away, and then starts running in an open field, as the camera pans upwards and the video fades away.
