Sorry I don't agree with you fellas on this. He spent good money on a Colston jersey (assuming its not a knockoff) and wanted it signed by Colston. Nothing wrong with that. Had he wanted just any old jersey signed by any old player, then it would have been a good joke-making people think they were getting a Colston sig. However that's not the case. He had a Colston jersey and wanted Colston to sign it.
edited to add: I know some of you have signed jersey's. I don't think any of you would find it funny to have your Drew Brees jerseys signed by someone else, and you would not have them framed and hanging on your wall. That is all this guy wanted, a Colston jersey signed BY Colston
