Trolley Dude: Shunning Fame?

For the first time in oh such a long time I, Little Stalky, saw trolley dude.  I saw trolley dude!  He's alive everyone.  Alive!  And doing what he does best: pushing a huge line of trolleys.  But trolley dude appeared to be trying to go incognito.  He was wearing sunglasses and a hat.  It was like he was trying to hide his true identity and blend in with the crowd.  I've decided that trolley dude must have become aware of his fame as trolley dude and is trying to avoid the fans.  He's trying to keep a low profile lest crazy women try and strike up conversation.  I watched him pass with awe and immediately alerted Mystical Roo to the fact that I'd just spotted trolley dude.  I then suggested to Mystical Roo that trolley dude seemed to be trying to go unnoticed.  Mystical Roo decided that it was down to the shaved head.  He figured trolley dude was ashamed of his baldness and was trying to hide the evidence.  Shunning fame or hiding a hair disaster?  It's just another trolley dude mystery.
