A friend of mine who is a natural has this wall of hats. He just goes out everynight, dances a bit, picks up some girls, when he spots a hat in the crowd he sometimes playfully takes it. Often the owner will take the hat back (whether male of female), but sometimes at the end of the night he still has the head on.
There's like 5 santa hats hanging on his wall, a joker hat with the bells, a few cowboy hats and a handful of top hats and charlie chaplin ones. Like a serial killer takes trophies, this natural takes hats.
Key of advice here.....make sure you go home with your hat
Hate to see a fellow PUA spending money on a hat just to have it end up hanging on some random dude's wall 99% of the time.
