co-worker: “You can get a sun tan.” (from photocopying stuff so often)
Me: “Or mutated cells and cancer.” (sorry for being so pessimistic, but I was thinking about my biology teacher from high school who said she was always scared of photocopying things because of all the radiation… she also pointed out that when you stand at the machine, the height of the machine happens to be near the region of body parts that affect your future children)
