"True Facts is not for children, nor is it for adults who don't act like children."

[@derp-construction3341]

I would beg for more frequent True Facts, but I think the product quality is well worth waiting patiently for.

[@siddharthsinha9300]

I'm surprised that apart from all the other jokes, noone appreciates Zefrank's skill with wordplay and grammatical humour: "Refuted - not just futed, they futed it again!" That one made me crack up!

[@hyrenaj2888]

"but fighting is a real bummer" is such a gem, like a diamond.

“A bit like a donkey swallowed a dial up modem” that’s EXACTLY what they sound like. There’s no better description.

[@kiwihame]

This was one of the most hilarious installments, in a series of hilarious installments. Thanks Ze, you're brilliant.

[@BoojeeRedneck]

I just discovered this channel and this was not the straight forward informative animal video expected. I laughed, I cried, I did a jig. Never seen anything like it. Perfection: writing, wit, narration, music. 10/10.

When I lived in Brunei as a kid, I'd often see Proboscis Monkeys while on safari through the mangroves, but the funnier story comes from when I visited a zoo in Malaysia. Essentially, i brought a toy jaguar with me as I wandered around the place, and when I got to the Proboscis Monkey enclosure and propped myself up on the viewing platform, they caught sight of the jaguar and quite literally went ape shit, the males roaring and flopping their red chillies towards the jaguars direction. In hindsight, probably wasn't that funny for them, but its hard to take them seriously when they were doing that.

'Flying style of a flopping trash bag that's caught in a whorl of wind." I love seeing the world through Zefrank's eyes!

[@mrg4388]

I could never thank you enough for your work. Truly utterly hilarious. Cheers me up on bad days. Please never stop making videos, ever.

"The bus kept going."

[@ALaughingWolf2188]

I’ve always loved Zefrank’s humor so much, because it’s like a Nat Geo documentary where the narrator can say LITERALLY anything without being fired while still sounding so professional. I don’t know how to better describe it, it’s just so damn funny to me with the way he talks

[@christinesmall894]

How am i just finding this channel. Love his voice, his great humor and all the information at the same time. Sweet stations

[@alishabounds8574]

Everyone could take it from Zefrank in terms of pairing professionalism with comedic honesty. I wish the world was more like this, making sure you're being true to the science of things and the facts but pairing it with the inappropriate humor that most people are thinking but hold back on saying aloud due to fear of being judged or looked at as unprofessional or something super serious. Thank you Zefrank, I've been here since teddy's operation, and literally stop what I'm in the middle of doing to watch these additions to the collection.

“sexual selection, which is the corner of evolution where all the weird shit happens” 😆 It so true.

[@giggityguy]

"Donkey swallowed a dial-up modem" might be the most descriptive phrase anyone has ever uttered

[@Rundalla]

The last bit about the statue had me on the floor, and earned you a sub! love the information and the way you present it!
