I love science jokes but the difference between biology jokes and chemistry jokes is huge i mean chemistry jokes are all cute like:
“Never trust an atom, they make up everything” and “Oxygen and potassium went on a date, it went OK” but biology jokes are really dirty like “I like sex like endoplasmic reticulum with ribosomes…rough” and “how do you make a hormone? don’t pay her” i mean srsly biology you could try to be less obvious

After the great flood, Noah let all the animals off the ark and told them ’Go forth and multiply!‘ 

A few days later, Noah went around and checked on all of the animals. Most animals were coming along quite well with their respective families, but when Noah came to the snakes, he was shocked to find that it was still only the initial pair. 

He asked them what was wrong and they told him they needed him to cut down some trees. Noah was very rightly confused and said 'Okay I’ll cut down some trees but why would you need me to cut down trees?’ The snakes then replied 'We’re adders. We need logs to multiply.”
