Fishing

Two village idiots Jimmy and Wayne are walking through their village when they see a man with a huge fish over his shoulder.

"How did you catch that says Jimmy?"

"With my mate" says the man with the fish. "He hangs you over a bridge and when the fish comes along he scoops it up."

Brilliant though the idiots we will try that. So Jimmy hangs Wayne over the bridge.

After 10 minutes Jimmy shouts down to his mate "have you caught anything yet?"

"No" came the reply.

After 20 minutes he calls down again, "have you caught anything yet?"

"No" came the reply.

Then after 30 minutes Wayne shouts up to Jimmy "Quick. quick pull me up."

"Why have you caught a fish?" says Jimmy,

"No" says Wayne,

"there’s a bl**dy train coming."
