Why do men spend do much time thinking about sex? The answer has puzzled scientists for centuries - mostly because they got distracted and started to think about sex, sex, sex instead.
Well, the answer has now been discovered: men's heads are loaded with big, hairy bollox.
"In a female, lots of grey, spongey stuff is inside the cranial delicate cavity" said a man scientist, "in men, their heads are full of big, dangly testicles. They are fucking useless things".
The women can use the sponges for bathing and storing useful things such as locations of great bargains and telephone numbers of friends, relatives and adorable babies.
Men, on the other hand, are just left with a head full of balls.
"Men spend the majority of their time trying to transfer these unruly bollox through their body. Sometimes they even force their way outside and gather in pairs - usually in the groin area....", continued the scientist before he just trailed off into thinking about sex, sex, sex again.
