One of the riddles we used to have painted on the walls of one of our classrooms in secondary school (with the last part added in :+ ):

What runs but doesn't walk,
has a mouth yet still can't talk,
has a head but doesn't think,
has a bed but will not sleep
and twists yet is not a riddle?

Took us 12 year old students a couple of days to figure out back then (despite it being terribly obvious in hindsight of course). So just wondering how many minutes it will take here :P .

The answer is

A river. As you said, it is pretty obvious. They run, have heads, mouths, and beds, and they often twist.

Is it a



A river runs, there is a river mouth, a river head, a riverbed, and there are rivers with twisting shapes.

  • $\begingroup$ Ah, that makes sense! I was hesitant to answer that at first, rarely schools have the real one in hindsight! $\endgroup$

Anyone with

young toddlers

knows that they:

  • tend to run instead of walk
  • have a mouth but don't talk
  • certainly have a head but don't think all that well
  • don't use their bed to sleep
  • will twist if you try to hold them
  • $\begingroup$ (+1): ha! I never thought of this! xD $\endgroup$
