IT Easter Egg - Voices in the Sink

This is in the scene in the first part of the movie (because there is two parts) where young Bev hears the voices in her bathroom sink just the red balloon inflates in the drain, pops, and sprays blood. Anyway, the first voice says "I'm Vicki Burrows" and the second "I'm Matthew O'Connor". You'll see that the names Victoria Burrows and Matthew O'Connor appear in the credits as part of the production crew(I can't find my tape so I'm not sure what specifically they are =) I caught it and thought it was kinda cool!
