About

'Sony PSP' was a YTMND by user boykicksgirl on April 1st, 2005. It featured an animation of a person playing Ridge Racer on the PSP and the UMD disc suddenly popping out. Early builds of the PSP were notorious for having the UMDs fall out when jerked the wrong direction, as demonstrated in the image.

The YTMNDs zooming text reads "It's not a defect! It's a feature!", and is accompanied by a loop of Franz Ferdinand's "Take Me Out", which is the song that was used in the PSP commercials in the United States.
