Bro, you know exactly how to do it. Cold approach starts with a funny out of left field entrance that has nothing to do with a pick up line.
I don't buy it, nowadays there's enough wimps around that openly admit they are into dominant women. Still how dominant the lady might be, a woman is always looking for a man, that brings more to the table than herself.
There are many ways to skin a cat, and every situation is different. But if you get a smile/giggle from the start your probability of continuing the conversation skyrockets. Whatever you do please don't come in with a dumb pick up line. And always warm up to the ugliest of the group. She is like the dolphin you must leave in the water while fishing so the others don't leave...

Dat's a rack a $2 ho's trying to up their price. Dude in middle prolly da pimp, gots his tie stuck in his shoulder holster. If u hear the martini glass hit the ground ur dead.
None of them has any class whatsoever. The one on the left is a fat pig. How on earth can that pig think she's hot? The chick left to the guy could be a tranny, look at those huge feet *gag*, the one right next to him is high on dope, next right is another fattie and last one on the right looks like a real slut. I concur with Banjo, a bunch of cheap ho's.
