It’s USC-UCLA week in sunny California and that can only mean one thing…the usual prank war that comes with it.

The first shot was sounded on Tuesday morning by vandals (likely those of the Trojan variety) who defaced a UCLA sign on the Westwood campus by painting over the “LA” with red spray paint and adding a “S” in between the “U” and the “C” with the same spray paint.

Check out a pic below.

But alas, UCLA responded later Tuesday night with quite the glorious, illuminated message for ‘SC.

Oh yes, that’s a few dorms on the UCLA campus getting together to create an unmistakable “F**k SC” message using their room lights.

Creativity and excellent planning/execution give UCLA the early edge in prank week. Don’t worry Trojans, you’ve still got plenty of time to exact your revenge.
