A joke is only funny if everyone laughs. This may not be the case but I wasn't there. Tell your friend to keep the autograph. You never now, it could be worth something one day to an autograph seeker. Case in point: I was attending a baseball game back in 1990 at the Rangers Stadium in Texas and it happened to be hat day. I got the manager Bobby Valentine to sign it along with the owner of the Rangers who was there. The owner of Rangers at the time was George Bush Jr. who later became a US president. Again, never throw an autograph away..
