本人原創笑話: Doctor, Master, Bachelor

En route her daily commute to work, Mary, a mid-aged Asian lady, found herself starting to enjoy the tram rides tremendously.

Surprisingly, the enjoyment came from the rhythmic vibrations and noises from the tram. It reminded her of the fun she shared with her husband in bed during the good old days.

One morning, a fellow passenger noticed the semi-painful expression on her face. Out of a genuine concern, he offered help:

   "Are you o.k. ? Can I get you a doctor?"

Mary murmured back - from her deep trance:

   "Giiiive me a master instead. Please!"

   "A bachelor would also be nice..."

The young fellow passenger was totally confused. He uttered a tentative response:

   "I have a bachelor degree in Asia Study, with a minor in Biology - if that is what you are asking."

Mary's body started to tremble. After a brief moment, she breathed a sigh of relief, opened her eyes, and said:

   "No wonder you are so good. Thanks to your help -  I've just had an orgasm."
