^I think kids have always done crazy and dangerous things like that to show off to their friends. The only thing that's changed is that they now show off to huge numbers of strangers. Although, granted, the larger audience and the presence of so many competing stunt videos could very well be creating pressure to attempt more extreme stunts.
Yeah this wasn't one of the more exciting episodes, but these guys are always fun to hang out with anyway. Especially when Tory is cracking corny jokes about Kari's melons. Lol.
I'd prefer to think that wasn't his intent, because that would be sexual harrassment of a coworker and it's nothing to laugh about. Certainly he was going for a cheap innuendo, but I think he was just joking with Kari as "one of the guys" rather than sexually objectifying Kari herself.
