Was bar hopping Friday night for a friend's birthday. When we were walking to the door I pass a girl, touch her arm, and simply say 'I like your dress' because she genuinely looked good in it and kept walking. She blushes a little and says thank you. We ended up staying at the bar. About an hour later the girl grabs my arm, kisses my hand, and starts flirting with me.

Made me realize that you don't always have to be smooth or witty to impress a girl.
