Some people, through no fault of their own, are unable to tell when someone is making a joke, no matter how obvious it is. One of these unfortunates is known only as “Bob”. He is one of the worst cases, the humor-impaired (™Dave Barry) individual who thinks he’s funny.
(To be fair to “Bob”, I just added the “Posts Where I Am Obviously Joking” tag to the post — this was a pre-tags Blogger post originally.)
