bloke driving down the road and his car packs up
gets out raises the bonnet and starts having a fiddle
"its the ht lead on cylinder 1" a voice says
looks round and cant see anyone
"its the ht lead on cylinder 1 im telling you mate"
looks round again and all he can see is a horse looking over the hedge.
is feeling nervous but jiggles ht lead 1 and sure enough car starts
calls in at a pub a few miles down the road for a drink to calm his nerves and barman asks him why he looks so panicky
"A horse just told me how to fix my car i think im going mad"
"was it a white horse" says the barman
"yeah" says the bloke
"you were lucky mate very lucky" says the barman
"whys that" says the bloke
"cos the black horse knows fuck all about cars"
