PSP graffiti appears on Tonight Show

Last night, while channel surfing, I came across "The Tonight Show." The title screen shown just before "The Tonight Show" went to commercials had the infamous PSP graffiti that Sony used to advertise the system some time ago. I'm not sure if this occurrence was just by chance and "The Tonight Show" just liked the image, or if this is subliminal advertising set up by Sony. While I have no proof either way, my instincts lean towards it being planned by Sony. After all, I doubt they got their money's worth on these graffiti ads originally.
