Producer/Consumer Implementation Using Thread, Semaphore and Event

I love to tell jokes and today, I finally came up with my own joke. here it goes:

I decide to make my first son a medical doctor so later on when I am old and sick, I can get medical care any time I need and for free..., in fact, better to make my second son a medical doctor too so I can get a second opinion.

here is another version of this joke:

I decide to make my first son a medical doctor so later on when I am old and sick, I can get medical care any time I need and for free..., in fact, better to make my second son a medical doctor too so I can get a second opinion. well, perhaps my third son should be a lawyer - in case something is wrong with my medical care, I can sue the first two for free.

if you happen to visit this page and read these two jokes, tell me which one you like...
