Yeah, I think the joke originally is to call someone with an unknown name Muhammed Kim because Muhammed is the most common first name and Kim is the most common family name.
♫ He roller-coaster, he got early warning
He got muddy water, he one mojo filter
He says: “One and one and one is three”
Got to be good-looking ‘cause he's so hard to see ♫
It was purely a guess, but I wondered if butterflies and moths rank up there in terms of number of species. Sure enough I checked Wikipedia and apparently it's the second largest order of insects.
Back in the day when I first discovered Wikipedia Random https://en.wikipedia.org/wiki/Special:Random, I was always amazed at how often a species of moth/butterfly or a species of beetle would show up. Like if the feature is truly and genuinely completely randomly showing me a page on Wikipedia, and assuming there's not even a page for each and every species of these insects, it was still impressively frequent.
Though, I just played with the link for a few seconds as I was typing this up, and I didn't get one single link to an insect, so maybe they've changed how they pull random stuff or maybe the ratios of insect to non-insect articles has changed over the years.
Also, if you forget someone's name, call them Muhammad. It's the most common name, and therefore, you're most likely going to be correct.
This is on the same level as "everyone has one breast and one testicle on average".
Most people have an above-average number of arms.
Yeah, I think the joke originally is to call someone with an unknown name Muhammed Kim because Muhammed is the most common first name and Kim is the most common family name.
Thanks for the advice, Muhammad.
