Great fulfilling and stimulating threads on this board

[Grudge]

like 'paste the last thing you copied'. Those really make my brain work and make me post things which make a difference!



I for one really enjoy reading the last thing some one copied, and I thank them for sharing it with us by pasting it here.

wow there are some typos in there I didn't notice

[Redd]

It doesn't make sense though it doesn't matter.

[Noyka]

It only doesn't make sense because my spacing got messed up and you have not had chemistry ma'am

[OJ8]

(±)cis-2-[(dimethylamino)methyl]-1-(3-methoxyphenyl) cyclohexanol hydrochloride



Looks like I'm not the only one with a lil' chemistry in my copypastezzles.

Hey ossi

sup scott

[Haunty]

So whose face is that with mustaine hair holding a panda?

[OJ8]

It's a pic of Dave Moustachne and Sexual Harassment Panda 2.0 having a coversation about warzone.

no i checked his figures and they are accurate

Quantitative chemistry.

Lava, do you have exams where you have to discuss how the laws of thermodynamics make you feel?

Nah, warzone was basically the Paki nbb equivalent of cat hallucination.

I am truly offended by the 3rd principle, I'll be writing a stern letter to my professor.

Have you ever browsed the posts in the music forum?

Ive always found them empirically banal.

boy this thread just turned into a sausage party
