Yeah I was really surprised they showed that myth, especially with how definite Adam sounded at the time of the incident that they never would, and how generally uncomfortable
the hosts all acted anytime the subject was brought up.
Makes me think the network might have pressured them to show it for ratings or something. Or maybe they just needed a second myth for the episode and that was the only one available.
In any case, it was kind of impressive that Tory's little homemade cannon was capable of such a powerful blast. It looked like the cannonball shot through the concrete wall like it wasn't even there!
