Human: I'm a bit confused about the difference between a clog and a jam. Can you help? Assistant: 
A clog is a blockage in a drain pipe or toilet that prevents water from draining properly. A jam is similar, but it happens when food particles get stuck in the pipes or toilets and cause them to stop working correctly. Clogs can be caused by many things such as grease, hair, soap scum, and other debris. Jams are usually caused by food particles like fruit seeds, egg shells, and pasta.
