Funny Joke: What is stress?

[Becky02]

You gave a lift to a beautiful girl;,
she fainted inside your car & you took her to the hospital.
Now that's stressful!
But at the hospital the doctor said she is pregnant & congratulated you that you're going to be a father.
You denied but the girl said you are
This is getting very stressful!
To prove that you're not the father, you requested a DNA test.
After the tests, the doctor said you are sterile and can't impregnate a woman:&
You are extremely stressed:$but relieved
But on your way home you suddenly remembered you have 3 kids at home.
Who the hell is their father

NOW THAT'S STRESS!!
