Being a Cat fan since the day I was born, thanks to my Godparents, I've seen a lot of gut wrenching losses.
10. 11 Ok State
9. 00 OU
8. 04 KU. I was working at Lowe's at the time, and had a store manager that played at K-State in the early 00's. He told me before the game LHC LHC Bill Snyder will never lose to KU. We were both pretty depressed the next day.
7. 03 Marshall
6. 04 Colorado. Joel effing Klatt was the QB IIRC. Hate his face.
5. 14 Auburn
4. 03 tOSU.
3. 10 NU. I wanted so badly to beat them one last time.
2. 12 Baylor. I was told I could no longer watch games at my in-laws house after that.
1. 98. I've told the story before, but this was supposed to be a bright spot for my family and friends after a really shitty week. My cousin who was my best friend died that week and we buried him on the day of the game. That day also happens to be my birthday. Lil Harry Doyle was heartbroken already and then it was completely shattered. Easily the most craptastic day of my life.
