I'm a current ISU student, but I was lucky enough to have a great interaction with Johnny Orr.
It was before the Alumni game against Nebraska some odd years ago (5 or 6 I think). We got to Hilton early to get in line for autographs, and were walking in the south doors when I noticed Johnny Orr was behind me! I held the door for him, and he said "Hey, thanks coach! " He noticed I had an ISU basketball, and offered to sign it for me, which I was thrilled about. My dad, who went to ISU from 80-84 and had been to many Big 8 tournaments , said: "Hey Johnny, who was that official who... " and Johnny cut him off and yelled: WOODY MAYFIELD (Which was the official who screwed us over against OU in the Big8 tournament, if I'm not mistaken). I'll never forget my dad die laughing at how fast he rattled off his name.
RIP Johnny.
