Facebook
Sometimes Facebook makes me laugh - especially when it suggests people I might like to be "friends" with.
For example, today my former brother-in-law was one of the people Facebook thought I might know. Ok, so I wouldn't expect Facebook to know I used to be married to his brother, but did he come up because we have several friends in common? Nope. It said I might know him because we went to the same university.
Weird.
Ever Have Someone In Your Office
Who is so incompetent that it would actually be easier if he never did ANY work because you spend more time correcting his errors than it would take you to do the project yourself? And sometimes, if you're very lucky, you'll get to make corrections TWICE because he only made some of your corrections the first time around.
