Two men are walking across a field and come upon a deep hole. "How deep do you think it is?" asked Fred. "
"Dunno" replied Pete ,"But if we drop a stone in it we'll get some idea when it lands."
"Good idea mate!" and with that he chucks in a stone the size of a cricket ball. They both cock their ears downwards but hear nothing.
"Sheesh , that's a deep hole" remarked Fred.
"Sure is , we need a bigger stone so we'll hear the thud at the bottom."
Fred finds a stone the size of a football and tosses it into the hole.Still they hear nothing.
"This is crazy! There's a railway sleeper , let's chuck that it" says Pete.
"That'll do the trick Pete , you take one end and I'll take the other!"
They struggle but eventually tip the railway sleeper into the hole. Immediately they hear the sound of approaching hooves and looking around they see a billy goat racing towards them , head down. Reacting quickly , they spring out of the goat's way just in time and see the poor animal disappear into the hole.
Nonplussed , Pete said , "Blimey , that was close!"
"Yep , can't see the goat surviving that!"
Next thing they're interrupted by a farmer,"Excuse me lads , you haven't seen a billy goat around here have you?"
'No", said Pete.
"That's funny", said the farmer, "I'd tethered it to a railway sleeper!"
