A man and a female parasitologist are having a conversation. They arrive at the topic of women in prominent positions.
The man states, “Well, I don’t trust anything that bleeds for seven days and doesn’t die.”
The parasitologist responds rhetorically, “You think that’s an appropriate statement?”
The man stupidly replies, “Hey, it’s just a joke.”
The parasitologist sneers and says “Yes, just a joke.”

A month later the parasitologist sees the man, he looks pale and feverish and is clutching his abdomen in pain. She strolls up to him and asks, “Do you no longer trust yourself?”
Confused the man replies, “W-what?”
She clarifies, “Remember you said you don’t trust anything that bleeds for seven days and doesn’t die; so, do you no longer trust yourself?”
The man is shocked, “How did you know?”
The parasitologist replies, “I could get into a lengthy and comprehensive lecture about why you have prolonged bleeding from your anus, but, hey, it’s just a joke.”
She walks away smiling, rolling a vile in her hand labeled Trichuris trichiura.
