"Quick Pick-Up Line" joke

An Old Indian was standing on the corner. A good-looking woman passes by, on the way to work. The Indian raises his hand in greeting and says, "Chance!"

The same thing happens several days in a row. The woman walks past, the Indian raises his hand, and says, "Chance!"

Finally, one day, she can't ignore it any longer, stops, and asks, "You're an Indian, aren't you?"

He nods.

She says, "I always thought Indians said' How!' as a greeting."

The Indian says, "Already know' how'. Just want' chance'."
