Gaaaaah!
Even if that WAS exaggeration, that was the worst acting in a tickling video I've ever seen. The experience of tickling someone becomes really rather deteriorated if the ticklee isn't ticklish or is only a slight bit ticklish. Even if they fake it WELL, it's still not the same. It can be compared to faking an orgasm, to an extent, really. While, yes, they did have some of the resistance-to-restraints movements down, their laughter was so blatantly forced that it almost seemed sarcastic. Maybe "interviewing" the women before making the video to determine ticklishness would be a good idea in the future. And if it turns out that they ARE ticklish, if you're making the video and you find yourself in a spot where they aren't ticklish, switch to someplace where they ARE. Sure, the tickling itself was real, like you said, but the reaction to it was horribly faked. These two videos would've been great if the girls didn't seem to be faking the experience so much. May as well have taken an audio clip of the cackle of Peter Griffin from Family Guy and stuck it in a loop over the video feed. I mean, if you're gonna fake it, go all out.
