Used to have these neighbors, and the dude, (Brandon) was this really cool guy that was all into lasers and stuff. Used to point his green laser at the mountains and you could see where the dot was all the way out there. Miles away. Was really cool.
Not only is he a cool dude, he also played this GREAT joke on a co-worker I had to share. Check it! (Thanks to Riley for the link.)
UPDATE: Video of the ordeal.
