Hilarious recording of (update: fake) telemarketer talking to a loop, if enough people did this companies might give up trying to sell things to us over the phone.
Many people on the Internet (including me from time to time) seem to have too much time on their hands. This page analyses a song in which Kate Bush sings the digits of Pi and finds out that she is actually referring to a ring of trees.
This discovery of the ring of trees at the precise location that I decoded from the song completes the quick verification that there is indeed hidden information in the song, and that I am not chasing illusions.
Improv everywhere has done some very funny things: sending 80 people into Best Buy dressed like the staff, suddenly moving in slow motion while shopping and creating a time loop.
