What if the reason most guys have such a juvenile sense of humour is that's nature's way of cheering us up from all the rejection we will face?

You got lucky. lol

@SW-User I think we're more accepting of our flaws, and can therefore find it easy to laugh at ourselves.

fart jokes, making things that look like cocks, pranking each other, stupid nicknames, seeing other guys getting hit in the crotch, all that cool stuff

@plungesponge Gotcha... But who has decided that it is juvenile? Maybe cock and fart jokes are a genuine subsection of humour rather than a low form.

@plungesponge Good point, but I have no answer. No matter how sophisticated you are as a man there will always be a fart joke you will laugh to
