Here are the four I've spotted this season, and I wanted to put it to a vote so there is a poll on the top right of the blog.
Your candidates for the Creepiest Cubs Mascot are:
#1 - Billy Cub
Not sure who this dude is, but if you google him you get an article titled: The Chicago Cubs Have an Unofficial Mascot… And He Is NOT a Pervert. My favorite aspect of this guy: his igloo cooler that he uses to collect tips.
#2 - The Hot Dog Guy
This mess of a mascot isn't even trying to work for the Cubbies, but I love the dude so I'm throwin him in anyway. He walks around trying get people to go to the Full Shilling up on Clark... when he isn't in the crapper, that is.
#3 Ivy Man
To be honest, I don't know a lot about this guy. He seems tall, likes to dress like the ivy and he generally just gives me the creeps.
#4 Ronnie Woo Woo
Most people who have gone to Wrigley know about Ronnie. He is homeless, somehow gets into every game, and the dude Woo! Woo! Woo's! wherever he goes. He got a little less creepy when the Cubs donated front teeth to him years ago, but still: a little creepy.
