There was a guy who worked for Blockbuster video. He found it to be a great but complicated job.
One day he was at the register and a older man came in and asked if he could buy a phone card. So the guy gave him a card, and he wrote him a check for $39.80. He then told him that it was 20 cents short, so he gave him 2 dimes.
Unfortunitely when he typed this into the computer, he missed the period on the keyboard and it came up as 20 dollars.
That night, the manager said that he was $19.80 short. The manager thought the guy had stolen it, so he fired him immediately.

And the moral to this story is:
"Guys get in trouble over missed periods."

Resolving to surprise her husband, an executive's wife stopped by his office.
When she opened the door, she found him with his secretary sitting in his lap.
Without hesitating, he dictated, "...and in conclusion, gentlemen, budget cuts or no budget cuts, I cannot continue to operate this office with just one chair."

theme of your jokes... hmm...
