When the sun shined through her dress, it was obvious she wasn't wearing panties... I could see her spanish moss.
Nurse: Why not, Doctor? Is there too much Spanish moss around her twat or something?
Doctor: Maybe so. Would you give me a hand on this one??
Nurse: Sure, doctor. Let me put on some gloves and I'll see if I can make my way through that Spanish moss. Pee-ooo!

There was an old whore from the Azores,
Whose cunt was so covered with sores;
That the dogs in the street
Wouldn't eat the green meat,
That hung from festoons on her drawers.
