Aglet. Thanks Phineas and Ferb!

I’m too old to know what Phineas and Ferb is, but when I was young I used to love knowing obscure words like:

• The indent between your upper lip and your nose is called the philtrum (more commonly known now because of piercings

• The recess on the bottom of a wine bottle is called a punt.

• The infinity symbol (like a sideways 8) is a lemniscate

• The cap on the pointy end of an umbrella, or any other tubular thing (including a pencil) is called a ferrule

• The space between your eyebrows is your glabella

Etc. Anyway, aglet was one of those. I was always so happy when I had an opportunity to use one (“Oh, man, my aglet broke!”).

Aglets.

Aglets, and it’s 100% due to Phineas and Ferb

I personally don’t know what they’re called but to my cat that’s called food.

Aglets. Terraria my beloved.

Aglet. Thanks phineas and ferb!

Telomeres for your shoestrings

Aglet. Another shout-out to Phineas and Ferb.

Aglet - Jimmy Neutron

Aglets

Easy. The 80s and older crowd will know this from some inherent eldritch knowledge or have no idea. But everyone else will know this from Jimmy Neutron.
scrolling through the comments, seeing Phineas and Ferb everywhere

I’m only in my mid twenties. Y’all need to stop making me feel old.

OP, they’re obviously called aglets.

Didn’t Phineas and Ferb teach you anything?

Aglets.

And their true purpose is sinister.

I knew a kid once who said when he grew up that he wanted to be the guy that puts the aglets on shoelaces.

I don’t know what ever happened to him, but I like to think he found his calling in shoe plastics.
