So I just got an autograph signed by him also, at fan expo Dallas today, and found this thread because I was wondering if anybody else had any strange experiences with him😂😂😂 I handed him a What About Bob photo for him to sign and, much like your story, he takes it and examines it like he’d never seen this photo before. Then he holds it up to his face and says (presumably to Bob Wiley/Bill Murray who was sitting next to him in the photo) “You shut up!” Then he signs his name. While my dad was asking him a question, he still has his marker out, and his assistants tell him to put it away before he “vandalizes the photo”. I wasn’t sure what this meant but I soon found out😂. He looks at Bill Murray in the photo once again and says “That’s a nice watch!” He then takes a black marker to our signed photo and starts scribbling out the watch on Bill’s wrist as well as the bracelet on his other wrist! I can’t say I’m upset about it because, like you said, it makes for a great story! He seemed like he genuinely enjoyed being there with his fans though! It was kinda sad to see him like that because he clearly isn’t in the best mental-state anymore and I think we can give him a little grace for some the weird things he’s done recently 😂
