Bert Mondays: Bert's Brother Bart

Last week we met Bert's nephew Brad; today his brother Bart comes to visit. I'm not sure if Bart is Brad's father or not, but I wouldn't be surprised if he were the result of a union between Bert's mom and Fozzie Bear. Although Brad has the same cucumbery nose and bushy bush of black hair as Bert, he's a bit more, well, gregarious.
