You have to understand that Moochie and his wife had no teeth. Oh, they each had a set of false teeth but, as explained to us, those were "welfare teeth" and so didn't fit right. Rather than hurt their gums by actually wearing the teeth, the Moochies simply carried them around in a brown paper bag stashed on the ledge of the car's rear window.
When supper was ready to be served, Moochie said to one of the kids "Go get our teeth" and the kid obediently ran out to the car to fetch the Big Bag o' Teeth. Moochie and the wife fished around in the bag, figured out whose uppers and lowers were whose, shoved them in their mouths, gobbled down their meals and then promptly took the teeth out again. Back in the bag for next time!
