Homer Simpson and Topology

"Here is the academic background of the writers of The Simpsons:

    J. Stewart has a bachelor’s in mathematics from Harvard and a master’s in mathematics from UC Berkeley.

    David S. Cohen has a bachelor’s in Physics from Harvard and a master’s in computer science from UC Berkeley.

    Ken Keelers has a PhD in Applied Mathematics from Harvard.

    Jeff Westbrook has a PhD in Computer Science from Princeton University."

Even better (from presentation of science) - Futurama!

Quoting:

"A coffee cup and a doughnut are homeomorphic because a coffee cup can be stretched into a doughnut. A doughnut cannot be a sphere because a sphere does not have any holes. Cutting is not allowed in topology but Homer finds a workaround by biting the doughnut, because if you bite the top off of an A and eat it, then the top no longer exists. Homer makes the doughnut and the sphere homeomorphic. And maybe that’s why he’s also called Homer."
