i don't know if you meant for the words to be written like that but there are some grammar problems there...this is more correct:

"Did you know that...
The Great White Shark has existed as a species for over 350 million years?"

i agree, but nice concept veintecerotres

i love this shirt. i would buy it. i always watch shark week. lol

Nice! Though what azygous said is true =/

i think it's wrong on purpose, like if you wear this t-shirt you're trying to be smart but you're still stupid.

fuck off bloodyrobot

the grammar problems can be work out
i speak spanish
my english sucks but, i'm tryin my best

i like it better with the bad grammar

well, good try veintecerotres, you speak English alot better than I speak Spanish anyway.

ahah I agree with Mily. I think its neat said like that.

its about time the sharks learn to speak english....

i am a fan yes.

this is the first of 5? I cant wait for the rest ooo let me guess

" the great BROWN girrafe have existed at 4 leg for over 250 million years."

back - " i still watch discovery channel"

I would buy this.

i dont watch the discovery channel.

i make typo's all the time;)
nice sharky vector!

hey

have to say i was disappointed when i clicked on the thumbnail...!

thought the shark might be bigger and on the right hand side of the shirt, maybe slightly overlapping onto the back.
my brother would've loved that. maybe that could be another version? i like the shark graphic.

nice design work though. well done.

oh yeh - people - could we have some tshirts with Spanish text? english is boring. "NO TRABACO" maybe?
any other languages welcome. but give us translations eh?

leave this design to the team at the Discovery Channel.

Yeah scratch this one but dont sniff it. Next

Err, funny concept, but let the Discovery Channel promote itself...

dope idea.. how about a grammar compromise : keep the first sentence "have you know that" -it's cool as it is and kinda looks like "I'll have you know that..." which is correct enough -and kinda funky...

Then change the second sentence to "The Great White Shark has existed as a species for over 350 million years!" (as Azygous suggested).

Compraré si habia este texto! 5!

If the bad grammar is on purpose, I don't think it is obvious enough that it is a joke.

who cares

i wouldn't throw 'great white' and 'group' on the same t-shirt. i thought you were referencing the band at first glance.

change the text on the front and then drop the discovery channel line. throw something on the back and it could be cool.

might want to fix the shark's expression, he looks scared.

i like everything about this shirt, except for the text on the back.
4.

yeah I thought it was a Great White shirt at first too

this is so gay, what could actually prompt you to put it on a shirt, what were you thinking, i imagine in a week you will look back on this design with a disgusted dismay that you were such an asshole as to post it.

This shirt reminds me of the shirts you see in other countries where they're trying to cop the english, but fall hysterically short. This falls short of hysterical.

I like the shirt, but with 'white' highlighted like that, it looks like its promoting anglo-saxon majority groups. Definitely needs better wording
