Did you hear that Stephen Hawking wrote a new book? It's called "Around The House in Eighty Days."
Stephen Hawking's New Book Title
Explanation
The joke plays on Stephen Hawking's physical limitations, humorously suggesting that a trip "around the house" would take him as long as a trip around the world. The humor comes from the juxtaposition of the grand scale of "Around the World in Eighty Days" with the very limited mobility of Hawking.
