I never said you did memorize jokes, nor would you have to. However, if you are naturally funny, you can probably tell jokes, which leads to the evo bio theory. Your status as a male is shown through actions. You subconsciously do them just as girls subconsciously read them a specific way. Yeah, you want a big apartment because you have enough money to afford it and might as well- but it symbolizes your status in society. Or, you don't have that much money and must use other strategies to mate- such as humor or boldness or whatever to try and snag a mate. It has absolutely nothing to do with coming right out and telling a girl, "Ok my social status is this because I live here and do this as a job so you can now weigh your options amongst all the males here and if mating me with me seems to be in your favor, call me." And also, in every strategy in every species, there are "cheaters" that try to emulate being one of the two, or "creative" as you might say. You have to be creativeness, lie about your profession, etc because you found that strategy to work. A male topi with small horns puts mud on them to make them appear larger- and it works. Isnt that creative? Not all topis do it, just a few. That's called a mating strategy.
