Busy busy busy

I have John's review at his school in an hour, and I'm still sat at my desk. So, Being quick and lazy, a nice joke for you.

A mother took her five year old son with her to the bank on a busy lunchtime. They got behind a very fat woman wearing a business suit complete with pager. After waiting patiently for a few minutes, the little boy said loudly, "Wow, she's fat!" The mother bent down and whispered in the little boy's ear to be quiet. A couple more minutes passed by and the little boy stretched his arms out as far as they would go and announced, "I bet her bum is this wide!"

The fat woman turned around and glared at the little boy. The mother gave him a good telling off, and told him to be quiet. After a brief lull, the large woman reached the front of the queue. Just then her pager begins to emit a "beep, beep, beep."

The little boy yelled out, "Run for your f***ing life, she's reversing!"
