Attending a USC Trojan football game doesn't come cheap.

Forbes magazine came out with a list of 25 college football teams that it considers the most expensive. The publication looked at the average price of football tickets and named the schools from really expensive to really, really expensive.

USC came in at No. 19, with ticket prices averaging $130. Last year, the Trojans were listed at No. 14, but ticket prices have dropped 12 percent. Is this because USC hasn't been performing as well as in the past? Who knows, but a ticket to USC's game against crosstown rivals UCLA costs about $242 on average, making it their most expensive game of the year.

Here's another interesting fact: Notre Dame is No.1 on Forbes' list with ticket prices averaging $294. However, Notre Dame's most expensive game is against USC with an average of $554.
