Excellent idea, especially for beginners and guys with lots of AA, I actually did a similar thing at spanish festival a few weeks ago, we were so bored out of our mid, so we started daring each other to do crazy things like approaching 2 girls and asking them if we could find faGItas anywhere or just approaching with an old school pick up line, we didn't care about the results we were just doing it for fun. But it helps a lot to your overcoming your AA and Social Anxiety, even Brad P. has a list for his student where he tells them to do crazy stuff, like start dancing or singing in front of a bunch of strangers, etc..
The weird thing happeed when we used a pick up like and the girls didn't not reject us then it was a real challenge wtf do you do next haha (it happened like twice and probably cz it was in daytime) it was still very fun
This post is very recommended for beginners
Cheers,
