A colleague of mine from the bookstore can laugh herself silly at any kind of unintentional physical pratfall. Thankfully, her closest co-worker obliges her by regularly tripping over things in the warehouse and almost breaking his neck in the process. Hilarity ensues.
Though I like a good, painful home video accident as much as the next guy, what can really brighten my day is well-executed linguistic silliness. I love it when someone goes through a lot of trouble to pull off a really lame pun (as in Airplane, for instance) but it can be even better when a funny phrase is unintentionally so and widely published. Have a look at the link below. Where a good proof reader be when needed is one?
