Arizona State University students, faculty, staff and passersby got an eyeful of green Thursday morning, as "A" Mountain changed colors overnight to the color of the University of Oregon.
The No. 2 Oregon Ducks are in Tempe to play the Sun Devils Thursday. A big crowd is expected for the 6 o'clock Pac 12 game.
The usually gold letter had temporarily been painted black in conjunction with the "blackout' promotion, which encourages all fans in attendance to wear black to the game.
The 'A' has been restored to its proper form, as members of ASU's Student Alumni Association hiked up the mountain this morning to repaint it black.
Conspiracy theorists wonder if the prank is actually meant to be a motivator for the Devils. Everyone else just thinks some Ducks fans pulled a fast one.
