Kids and adults suffering from arrested development (more common than ever before) laugh when someone trips or falls. It shows what kind of person you are and the kind you associate with. Enjoy.
I'd say that an inability to think logically would be a far greater sign of this so-called 'arrested development' that you've clearly been so busy researching. And as usual, your post serves as a perfect example. I'm quite happy for my words on here to be taken as an indication of the person I am: I have no qualms about treating Mike’s 'devastating' tumble with a bit of levity. He's a grown man, he wasn't injured, and he's very well-known for taking himself far too seriously. Furthermore, it is with pride that I can state I have the ability to laugh at myself and associate with like-minded individuals.
Now let us hold you to this same standard that you apply to others: your words on here will remain long after you're gone, and I do not even need to attempt to cite the innumerable examples which depict you as a truly disgraceful person. The mere suggestion of doing so should make you put down your stones and retreat back inside your glass house. Enjoy.
