Personally I find these humane mouse traps rather ineffective. Better to lay down some glue and when you hear the critter scream you take a shovel to his head.
I read that Maria is in Chicago to tape an interview with Gayle for one of the two surprise shows. Oprah, Gayle and Maria have all been friends since they worked together in Baltimore so I think they'd talk about Oprah's early years.
Maria WAS there but only in paying tribute to Oprah...she was one of many many celebrity guests last night. She looked great and held herself together very well!
