A woman rigs up a veternarian at 1:00 in the morning.
Woman: Doc, the neighbour's dog and my bitch, you know, they are stuck. I can't separate them. What should I do?
Doctor: Try hot water.
Woman: I tried, but it does not work.
Doctor: Try cold water, then.
Woman: Doc, I tried that too,it just doesn't work.
Doctor: (after a moment pause) OK. Let me talk to the dog.
Woman: (surprised) Will THAT work??
Doctor: Well, it worked with me.
