Crap Disease
Crap Disease is when you eat crap or watch/read crappy stuff. The Crappy picture of Crap shown to the right is sentient crap, a side effect of Crap Disease. Eventually, you will start to spontaneously crap sentient crap at random intervals. Rarely, it's been recorded that people will spray a constant stream of crap for 30 minutes. The final stage of crap syndrome is crap starting to surround you, and eventually turn you into crap.
P.S. By reading this, you now have crap syndrome.
