I really enjoyed this episode, though I would never again use an Ouija board. Like a lot of kids, my group of friends experimented with one when I was about 14 or so. Much like was mentioned on the show, it started as harmless fun. The entity/board did provide a lot of accurate answers to questions like "What is Steve's favorite color?" and "Who does Scott have a crush on?". However, things did get a bit creepy after several sessions. When we started asking for signs or proof of a spirit's presence, a couple of weird incidents took place.
The first one took place when the entity instructed us to wait outside our house for 2 minutes. The five of us who were there did go outside, and I remember checking the clock as we stepped outside and shut the door behind us. We used the second hand on a watch to count the two minutes, and returned inside feeling crestfallen that nothing had happened. However, when I checked the same clock upon entering the house, it showed that more than 5 minutes had passed. Not exactly the movie Poltergeist, but it blew our minds.
Then, a few months later we started messing around with the board again. Again we were instructed to go outside, and this time walk toward the east. We didn't know how far to walk, but we ended up walking into the woods, a total of about 200 yards from the house. Right then, we literally stumbled on an enormous, dead raccoon in the middle of a stream. Of course, we were freaked out again.
There were quite a few other creepy sessions, but I was done with Ouija shortly after that. It just creeped me out.
