When I was a kid, went to a signing at local store. Was like 10. Asked for a picture with him. Said 'No'. Waited in line forever, he took 'breaks' every few minutes that were a few minutes themselves. I got my poster signed, but he ended the signing early and sent a bunch of people away.
He used to be a jerk. Seems like he did a 180 and became an awesome member of the community, but the only personal interaction I had with him crushed my image of sports stars as a kid.
