4 best moments from the USC-UCLA rivalry

UCLA and USC square off this Saturday evening in Pasadena in what is known as the "The Crosstown Showdown."

The series dates back to 1929, when the Trojans crushed the Bruins 76-0 but since then, the contest has often determined the Pac-12 Championship and a berth in the Rose Bowl

In honor of this weekend's clash, here are four memorable moments from the series:

1996 - UCLA 48, USC 41(2OT)

This was the first and only time a game between the two teams has gone into overtime. The Bruins trailed the Trojans by 17 points midway through the fourth quarter. USC had a chance to win the game on a field goal at the end of regulation but defensive tackle Travis Kirschke blocked the attempt. In double overtime, running back Skip Hicks ran in a 25-yard touchdown for the winning score.

1969 - USC 14, UCLA 12

Both teams entered the game undefeated, each with one tie to their record. USC was ranked No. 5, while UCLA was one back at No. 6 with the winner headed to the Rose Bowl to face Michigan. The Bruins led with under two minutes to go, but Trojans receiver Sam Dickerson made a catch in the back of the end zone on fourth down to give USC a 14-12 victory. Many believe Dickerson was out of bounds when he made the sliding snag. The Trojans would go to their fourth straight Rose Bowl and defeat the Wolverines 10-3.

2006 - UCLA 13, USC 9

UCLA was having a tough year with a 6-5 record, while USC was ranked No. 2 and one win away from advancing to the BCS Championship against Ohio State. The Bruins' defense came up huge, especially late with the Trojans driving. Eric McNeal would intercept a John David Booty pass with 1:10 remaining to seal the game and end USC's 63-game streak of scoring at least 20 points.

1967 - USC 21, UCLA 20

This game is known for two things: "The Game of the Century" and "The Run." UCLA AND USC were ranked No. 1 and No. 4, respectively, and both had Heisman candidates - Gary Beban for the Bruins and O.J. Simpson for the Trojans. Beban and UCLA would take a 20-14 lead in the fourth quarter, but that's when Simpson provided one of the greatest plays in college football history. The running back ripped off a 64-yard touchdown run to give USC a 21-20 victory. USC would beat Indiana in the Rose Bowl and win the national championship.
