Here is something that I have been wondering about.
In 'A Big Ball of Garbage' we learn that the main use of the Internet is, just as in 1999, to dounload pornography.
In 'I Second That Emotion' we learn that Leela plays a prominent role in Zapp Brannigan's Web page, and that it is clear that Leela is, shall we say, not a virgin.
So what exactly is the nature of this evidence? Did Zapp have hidden cameras? And am I the only one who would LOVE to visit his site?
