When I was about 7 or 8, my mom was taking a psychology class while finishing up her degree. One of the subjects was about fears/phobias and as part of a learning experience, the professor was going to bring in several snakes to class (boas and other non-poisonous ones) and add to her ongoing statistics about how many people in the class were afraid to touch the snakes. My mom knew I liked snakes, so she asked if it was okay if she brought me to class for that day, and the prof. agreed.
As expected, most of the class members were afraid to touch the snakes. I was dying to play with them, so my mom finally asked if it was okay if I touched them. Again, the prof. agreed. After the rest of the students saw a young kid playing with the snakes, pretty much all of them finally decided that the snakes were okay and I think everyone eventually ended up touching them.
Apparently the prof. decided to not use the data from that day since I caused the statistics to be completely off the norm. :)
