Discussion Headscratchers / MythBusters

I know I've asked this in the Headscratchers page, but since there were no replies, I'm going to ask this again here:

In the episode where the team was testing whether or not swearing/cussing is a natural pain tolerance for people who blurt them out, and they "confirmed" it, I can't help but find something off about that experiment. Yes, I can understand that many (I mean MANY, not EVERYONE, because not everyone knows everybody) curses when they get hurt, angry, and/or surprised, but what I found out was when they do that experiment, they ALWAYS start with not-swearing the FIRST time, and then swear the SECOND time, all done by the very same person each. So why is it that they don't have some of them do the other way around (swearing first, not-swearing second), each person do the very same method the second time as they did the first (either swearing/not-swearing twice), and/or at least hire a group of people splitting into two groups (one group focusing on swearing, the other group focusing on not-swearing) and having them doing that experiment ONLY ONCE PER PERSON? For a while, I can't help but noticing that the experiment they did was one-sided, and, from my personal experience, one-sided experiments doesn't prove chicken crap.

I think you are confusing Bruce Lee with Urameshi.
