Things you think are jokes until you realize they're not

I used to say, when people would cut on me for smoking through a cold, which hel-lo of course I always did--though I did switch to lights when I had pneumonia--I used to say to them, "smoking makes it an inhospitable environment for germs" or something like that. I have a theory, in fact, that the only people to survive the environmental apocalypse will be junk food-eating smokers. So yeah, I would say that but I would be at least half way kidding. Now, I have quit smoking, and I am here to say that's no joke. Never have I been so darned sick. Fer cryin' out loud. Truly I find myself thinking I may have to start smoking again just so that I can feel well.
