Fry: So you're telling me they broadcast commercials into people's dreams?
Leela: Of course.
Fry: But, how is that possible?
Prof. Farnsworth: It's very simple. The ad gets into your brain just like this liquid gets into this egg.
(He holds up an egg and injects it with liquid. The egg explodes, covering him and Leela in yolk.)
Prof. Farnsworth: Although, in reality, it's not liquid, but gamma radiation.
