I took all of these from another thread and alphabetized them for easier reading. Some of them are more for fun than practical use but we all need a laugh every now and then. If you want to see who is credited with adding them to the list click here.
If you have some that need to be added to the list then post them or PM me and I'll get it updated. I want to keep this first post as the master list.
