A woman was trying to board a bus, but her skirt was too tight and she couldn't step up. She reached behind her and lowered the zipper a bit and tried again. The skirt was still too tight. She reached behind her and lowered the zipper some more. She still couldn't get on the bus and lowered the zipper a third time.

All of the sudden, she felt two hands on her butt, which proceeded to push her up onto the bus.

She spun around, with anger in her eyes, and said very indignantly, "Sir, I do not know you well enough for you to behave in such a manner!"

The man smiled coyly and said, "Lady, I don't know you well enough for you to unzip my fly three times either!"
