In my lifetime:

1961
1963
1964
1965
1969
1971 (ruined a perfect season)
1972
1974
1977
1978 (A tie...but cost us the SEC)
1979 (Almost won the SEC with a 1-3 non-conference record.)
1983 (Boy did we miss Herschel that day)
1984
1986 (Yeah, we won...but got hosed.  Literally.)
1987
1988
1989
1990
1993
1995
1997 (This game stung.  Just hammered the Gators and came out flat.  I believe Hines Ward got hurt on the opening kickoff.)
1999
2000
2001
2004 (Cheap shot on Reggie Brown missed by typically inept SEC officiating crew)
2005 ( Luckiest 4th and 10 in the history of the series.)  

I hate Auburn.
