After having fixed some typo on Wikipedia, I overcame my shyness and added my bits to it. I have always found funny the way the word “Jack” is used, so I added here some missing usages. It was hard to find something silly enough to be a good start but finally I have found it :).
I have added:
- Car Jack
- Jack Frost
- Jack knife
- Jackpot
and some Jack that are stil to be added are:
- boot Jack
- Jack-in-office
- Jack ketch
- Jack staff
- Jack towel
- screw Jack
I suggest reading http://www.thefreedictionary.com/Jack and http://dict.die.net/jack-in-office/ because the hunt is still open :).
Nice!
