So this year I decided to give my co-workers coffee mugs and write something (and maybe paint) on them as part of their Christmas presents.
I work in a microbiology lab and thought it would be a good idea to write something related to microbiology... (Here are the main 3 bacteria types that we mostly work with: staphylococcus aureus, Pseudomonas aeruginosa, E. coli) so something relate to one of these might be good, but it doesn't have to be related - anything related to microbio works!)

So any funny quotes you guys know of that I can write?
