Doctor: Nurse, come in here please! I can't place a catheter in this patient!
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!
