A family of moles were marching through their tunnels, nose to
tail, with daddy mole at the front followed by mummy mole, daughter mole
and little baby mole. Suddenly baby mole shouts "I can smell treacle" so
they go on to the next wide point of the tunnel, all shuffle past each
other and start off in the opposite direction.
After another 100 metres, baby mole shouts "I can smell
treacle" again so they all carry on to the next wide point and the whole
changing directions procedure takes place again. This happens twice more
and on the 5th occasion, daddy mole comes back and gives baby mole a hell
of a clout. "What was that for dad?" he asked.
Daddy mole said "You silly bugger. That wasn't treacle you
could smell, it was mole asses".
