Upon further review, read Dennis Dodd's CBS Sportline column:
Months later, 'Canes interference call looks right
 

This exchange took place at the Eddie Robinson Coach of the Year award presentation. Tressel was the recipient, and Winslow Sr. was the presenter:

Kellen Winslow, Sr. asked Tressel these two questions, and did so sarcastically:
1) Where can I get one of those sweater vests?
2) How do you define pass interference?

Tressel responded: "First, maybe if you get in the weight room and work out a little bit, you can borrow one of mine.

And the definition of pass interference? Well, when those guys in the black and white striped shirts, and funny pants throw out one of those yellow hankies, then it's pass interference."
