David Foster Wallace's Tennis Racket

Origin
David Foster Wallace (February 21, 1962 – September 12, 2008) was an American author of novels, short stories and essays, as well as a professor of English and creative writing. Wallace is widely known for his 1996 novel Infinite Jest, which was cited by Time magazine as one of the 100 best English-language novels from 1923 to 2005.

Effect
The tennis racket was used by Wallace while writing Infinite Jest during his brakes from writing. When held, the user's brain will begin to go into overdrive. They will tell extremely long stories without even thinking. The stories have been seen to have many twists, turns, and the user will often stray from the original story to talk about something earlier in the story.
