“One type goes roundsies and the other sort goes upsydownsies”

I can’t keep up with all these complex scientific terms.

[Campiclatch]

The "butt, sorry, but" joke will never get old

[paulpach]

"Think about Goldie Locks with a stiffy... or don't"
I died

[HumbleMemeFarmer]

Box jellys don't just indiscriminately hate, they actively seek out places to be more efficiently hateful. I respect that dedication.

[SalemArc]

*"Ribbed for pleasure version of itself"* is not a phrase I was expecting, even though I've been watching this channel for years.

[morency_music]

"Fish are just ficient, but jellyfish are jelliefficient!"
Fucking brilliant

[theoriginaledi]

I've said it before and I'm sure I'll say it again, but MAN. When a single human can teach you a ton of science while simultaneously making you laugh until you have tears in your eyes, that's something truly special. I've encountered that amazing gift twice in my life: My general physics professor in college (RIP Dr Khosla) and the inimitable Ze Frank. Respect to both of them.

[NatYourAverageNerd]

In a video all about jellyfish, the most surprising fact I learned was that there is a fish species legitimately called "Boops Boops."

[anthonywestbrook]

I am so glad that you created a separate channel for classroom appropriate editions, so that we get the unbridled, unhinged, immature jokes I love so much.

"It's either a stream of snacks or a bidet. Win/win!"
Ze Frank, 2024
🤣 🤣

[alessandradigraziano]

The "I asked one of them once, he replied h, jh, mhkmjhjdhidfj" killed me. You always brighten up my day and teach me new stuff. Thank you!

[angiehornshaw]

'Macrame project on an acid trip'..I can attest to this. Nobody liked their Christmas presents that year...

[JoeVO]

the fact that some jellyfish have actual functioning image forming pseudo-eyes astounds and terrifies me

[julakenley]

"Weaponized pubic hair" got me... but also, "The last thing I need is a call from your mom saying you stapled your gonads to your lapel, like it's MY fault!"😂

[michaelccopelandsr]

Bringing smiles to people is truly noble work. And Ze does it while educating us. Thank you, Ze.

[MusicFromAnotherTime]

We always talking about Gonads, but why we never talk about StayNads?

😭

[wolfgangjr]

Omg. Another informative and hilarious episode. Especially with the ending credits. Please never stop.

[RemiWebster]

"It's either a stream of snacks or a bidet. Win-win!"

There are no good times to take a drink during a zefrank video, cuz you're going to hear something like this and risk choking, spraying your computer, or power-washing your sinuses.

"I will call you Squishy, and you shall be mine! And you shall be my Squishy!"

[rabidkoalaz]

Out of all my subscriptions, this channel is the one that gets me the most excited when an update pops out.
