A chemist walks into a pharmacy and asks the pharmacist, "Do you have any acetylsalicylic acid?"
"You mean aspirin?" asked the pharmacist.
"That's it, I can never remember that word."

A physicist, biologist and a chemist were going to the ocean for the first time.

The physicist saw the ocean and was fascinated by the waves. He said he wanted to do some research on the fluid dynamics of the waves and walked into the ocean. Obviously he was drowned and never returned.

The biologist said he wanted to do research on the flora and fauna inside the ocean and walked inside the ocean. He too, never returned.

The chemist waited for a long time and afterwards, wrote the observation, "The physicist and the biologist are soluble in ocean water".

Two molecules are walking down the street and they run into each other. One says to the other, "Are you all right?"
"No, I lost an electron!"
"Are you sure?" "I'm positive!"

Organic chemistry is the study of carbon compounds,
biochemistry is the study of carbon compounds that wriggle.

Classification of Chemistry
Physical Chemistry: The pitiful attempt to apply y=mx+b to everything in the universe.
Organic Chemistry: The practice of transmuting vile substances into publications.
Inorganic Chemistry: That which is left over after the organic, analytical, and physical chemists get through picking over the periodic table.
Chemical Engineering: The practice of doing for a profit what an organic chemist only does for fun.
