The Couch Tomb in Lincoln Park

You visit the Lincoln Park Zoo with your family (because it's free) and when you get bored and want to explore other areas of the Lincoln Park Community Area. You walk around and see a tomb with the name "Couch" on it and wonder "what the f*ck is a tomb doing in the middle of everywhere?!" You could read the signs around it and learn what it's doing there, but you don't want to because you're in a hurry.
Has this situation ever happened to you? Have no fear! This episode explains why that tomb is there and, more interestingly, what's inside.
