The greatest pickup line ever?

This is an older one but I haven't seen it posted here on ECCIE yet. What are your thoughts on this tactic? It has only ended with throbbing cheek complete with a red hand print on the side of my face when I try!

Marcus, its all traffic, sales and the law of averages. Studies show that if you try a line like this, about 8% of the time you will succeed.

I dont get slapped much the other 92%. Mainly I get told to go fuck myself.

But, this is a legit strategy.
