This morning, as I blew about 5lbs of crap out of my nose, I thought "great, I'm catching something".
Then I thought about how stupid that saying was. Typically when you "catch" something, its a conscious decision to grab and hold onto something that is thrown to you. While nobody bats an eye when you say: "I caught a cold", they would probably avoid you and label you a nutcase if you said "I caught a pile of poop".
Although germs can be "thrown" at you, typically by an inconsiderate co-worker that comes to work sick and then hacks and sneezes all over you in a meeting that you didn't want to attend in the first place, I'm pretty sure you have no choice in whether or not to "catch" those germs as they are sprayed on you at a rate of 40 mph. Its like trying to outrun a speeding car. So you should just say: "some inconsiderate bastard sprayed me with their cold and contaminated me." Of course, that's a really long sentence but if you just said "I have a cold" then people will label you a plague carrier and blame you for everything as if you spontaneously contaminated yourself with a cold virus.
So, I guess having a cold is all about blaming someone else for your illness, and that you couldn't possibly be sick for no reason, but that someone threw a cold at you, and like a dumbass, you caught it without thinking.
I'm going to start a new trend:
