So for those of you who haven't played DOTT (for shame), I'll explain. Bernard needs to get Dwayne out of his room, so he gives him a letter which reads "You're brilliant. What a novel design. Come to Baltimore at once." Dwayne falls for it, which gives Bernard a chance to ransack his room.
Also, you've probably noticed that there are a few more buttons over to the left there. They're mostly other webcomics I like. As well, one of them is for the DOTT / Maniac Mansion website "DOTTcom." It's a good place to go to if you're looking for general information on DOTT or Maniac Mansion (which is also a really good game, though obviously nowhere near the brilliance of DOTT).
As always, if you've got any questions or comments please don't hesitate to email me.
