Quick Answer
Science jokes use lab vocabulary, such as atoms, cells, bonds, forces, and bacteria, as raw material for puns.
This page has 90+ original science jokes: funny chemistry, physics, and biology jokes, bacteria and germ jokes, earth science and marine biology jokes, biochemistry and vet jokes, nerd one-liners, and a short set of engineering jokes. They’re clean, easy to read aloud, and written to make both scientists and non-scientists groan.
