Women are not lazy. They cook, clean, complain about inane things, work to make men their personal bitchs, plus whatever else they feel like doing.
However a majority of things they do are only for attention, or the illusion of attention. This is why you see alot of crappy videos on youtube that make you want to do something. However, all you really can do is post a comment. Regardless of what you say, you are paying them some attention.
Ergo, they don't have to be funny.
