My jokes:
1. I was changing my son's pull up diaper and I was thinking - "may be all men are dreaming about this size of underwear. All you have to do is wear a diaper and pee - pee in it".
2. My girlfriend tried Viagra, she said : "Don't ask me how and where I got it." She said it actually feels like drinking coffee and being kind of happy all day.
3. I used to work in Sberbank in Russia and once in a while I had to replace bank employees from different branches who went on holidays.
In one of those branches I meet a woman who said that her son was in special army force and had contact with radioactive energy and now has some health problems.
I told the woman: " I am almost a doctor, I read the Big Medical Encyclopedia, I know everything".
The very next day I meet that woman's son and we had an eight hours first date.
After the man was calling me at work in the main bank again and again, nonstop. The bank manager asked me, why when we send you to any branch, the men are always calling you?
Finally, when the man called me again at home, I said, its over, don't call me an more.
In a few days, my father, who is a psychiatrist in a local mental hospital called me and asked, what I am dong to his patients.
That man was my father's patient and was just successfully treated for schizophrenia and successfully released from the hospital. And now he is back and all he was saying was my firs and last name.
