POP QUIZ F.artMed would like to ask which of these three creatures have the biggest testicles and why. Is it the gorilla, Man or the chimpanzee (arranged in order of the biggest animal to the smallest)? F.artMed took to the streets once again. Do make a guess before scrolling down. CharKway Teow Ah Pek at Ayer Rajah Hawker Centre. Reporter: So what's your pick? Ahpek: What testicle you talking about? Only sotong have testicles la. 8 testicles. Reporter: No. No. Those are not testicles. Ahpek: Correct la. Sotong, 8 testicles. Human no testicles. Monkey also no testicles. Reporter: No no. Humans and monkeys are primates, with 2 testicles each. The squid has 8 tentacles. Ahpek: Ah tentacles. Say clearly la. Humans have 2 tentacles right. And I see so many ci ko pek. So humans hor the sex drive is confirm high. So must be humans got biggest tentacles. Reporter: You mean testicles? Ahpek: Tentacles la, lampar. Reporter: I'm sorry. But you're wrong. Ahpek: Long? Yes correct also. Humans got the longest one also. Reporter: No no you're wrong. Ahpek: Oh yes I am. That's why my wife so happy. Come have some pig intestine soup, good for your sex drive. F.artMed decided to let the AhPek bask in his glory and left. While moving on in the MRT, F.artMed realised that the MRT train is getting very hot and stuffy. Last time, the only sliver of water on a passenger's face was drool. Now, it's sweat. And it's not just one passenger. Maybe it's just the weather. But F.artMed suggests to SMRT to just turn up the air con in the trains yeah! The answer to the Pop Quiz is the chimpanzee. The chimpanzee females are the most non-filial and most likely to stray. So the males, in order to ensure their genes and traits are passed on to future generations of chimps, need to ejaculate a lot and spread their seeds to as many females as possible. That's why, natural selection results in the preferred trait of the large testicles so that the fittest will survive and mate. Humans come in second, because the human female, aka women, are not as astray as chimps, but they are not very filial either. So men develop a sizeable testicle. I mean 2 testicles. Gorillas have loyal mates, so they in fact have the smallest testicle among the 3 primates. Mic Man: Welcome back Champions League. ~
