A blonde is walking down the street
With her blouse open and her right breast hanging out.

A policeman approaches her and says,
"ma'am, are you aware that i could cite you for indecent exposure?"

She says, "why, officer?"

"because your breast is hanging out."

She looks down and says, "
Oh my goodness!
i left the baby on the bus again!"
