Leela and the Genestalk

As they are climbing Leela's "hair", Fry and Bender cross paths with Adam West and Burt Ward, who played Batman and Robin, respectively. The entire scene is a parody of a similar recurring campy scene featured throughout Batman e Robin (1966): Batman and Robin would be scaling a wall (literally "walking" up the wall) and a window would open and some random celebrity would have a brief cameo.

Why would the sink's water pipe from the giant's room lead to the Bridge of Mom's ship? Everytime the giant uses the sink, it would flood the Bridge.
