Chiste...chiste

Un chistesito que me mando Tracy:

Doctor Dave had slept with one of his patients and felt guilty all day
long. No matter how much he tried to forget about it, he couldn't.
The guilt and sense of betrayal was overwhelming. But every
once in a while he'd hear an internal, reassuring voice in his head
that said:
"Dave, don't worry about it. You aren't the first medical
practitioner to sleep with one of their patient and you won't
be the last. And you're single. Just let it go.."
But invariably another voice in his head would bring him back to
reality,


Whispering:....



Dave.............






...............you're a vet".
