Limerick

This morning I woke up with the memory of having composed a limerick in my sleep, except I can only remember the first two lines and the fifth line:

One day I was out hunting fox
With Adam Smith, Ingles and Marx
????
????
So Marx offered me used socks

Of course now I have no idea if I really ever had a third and fourth line. I do have the impression that the third and fourth lines would have made made Marx offer of used socks inappropriate, and been a bit of a take on Marxism and communism.

So can anyone else think of what these lines might be? I won't be disappointed to learn that this is not original, since it is clearly something my subconscious dug up.
