>>>>Toward this end we seek professionals who can think creatively and get the job done without supervision. We do not allow smoking in the office. We do not eat at our desks. We frown on personal phone calls. And we adhere to an office professional dress code. The culture here is generally pretty grown up and serious. However, at the same time we have a great group of talented people and very low staff turnover. The two members of the existing computer team have over fourteen years combined employment here.

Yes, that's the point of this joke <g> The question How. I'm wondering why should I always explain the jokes I'm making. I guess it's either my peculiar sense of humor or the fact that I forgot to put a smiley in the anekdot I was telling.

BTW, I read this joke long time ago in some English jokes book.

There were few others, let me try to remember them:

Little boy riding his bicycle:

Mom, look, I'm riding without legs...
Mom, I'm riding without hands...
Mom, I'm without teeths...

The woman on the market:

How much does your plums cost?

Please give me two plums.
Oh, I see you're making a party.
