The Y chromosome

I always figured boys/guys act the way they do because they weren't taught manners. It is never attractive to hear anyone belch out the ABC's or high five at the smelliest fart. I have found that it isn't a lack of manners, though, but the Y chromosome, is to blame. They just can't help it. It starts at a young age; in my study the average age is 3 years old. This is just the beginning. When they pretend to belch after every bite and laugh uncontrollable at their little farts. They then continue to develop and perfect their technique over the course of the next 10 years, so by the time they turn 13, they are sitting next to their fathers and high fiving each other's smelly farts.

I just have to say, it isn't my fault. I tried. It just can't be helped.
