Had an engineer friend that went to Germany on a military installation job with other co-workers.
They all went to a restaurant to eat dinner the first night.
Not knowing any German, he ordered by number from the menu, Item number 9.
The waiter, thought he said 'no' when he ordered, so he didn't bring anything!.................
I used to get people calling me and begging me to not answer when they called back so they could play my outgoing message for a friend...
