World's Smartest Garbageman
Dilbert's garbageman is frequently described in the comic as "the world's smartest garbageman". He occasionally solves extremely complex problems for Dilbert and in various strips has developed several futuristic inventions. In the TV show, it is revealed that he is the only garbageman for the whole city and is able to collect for all houses through "shortcuts".
Note, the garbageman doesn't have a name, moving in and out of the Dilbert's life anonymously. The chances are good that he's one of the key developers working with Dogbert.
I wonder which one communicates with Gavin.
I wouldn't be surprised to see a Mt Bert in the very near future.
Bert Baccarat anybody?
