I've had the same circle of 6 close fishing friends for over 35 years and we've had some fun and laughter fishing. A couple of times I remember we're at my expense.
We'd go fishing regularly in the summer and I kept getting a nasty whiff of something unpleasant but couldn't work out what it was. Anyway one hot day we're all sat round having a chat and a brew on the bank and I asked them what they thought the smell was. I noticed a few giggles and wry smiles. "Come on, what the fuck is that smell, what have you done?".... Silence, then a few more smiles and giggles. I sussed out the stench was immediately around us and started going through my tackle. I unzipped my rod holdall and tipped it upside down to find a pool of fishy slush fall on the floor. One of the rotten cunts had found a dead Jack pike and stuffed it down one my rod tubes!
The other time was when we all arrived to the fish the Trent. We turned up at the same time in two cars to leg it to the bank fully laden with full kit and buckets of maggots casters and hemp. I was young and fit back then, pretty strong too and very eager to march across 3 farm fields to get to a good peg. I arrived and collapsed, absolutely fucked, sweat dripping off me. My mates started laughing mischievously!...I opened my Riva box to find a fuckin' big drystone wall slab had replaced all my kit inside! When they saw me open my box to see my face they were pissing their sides in laughter. I told them they go get fucked if they thought I was fishing a duff swim. My mate Mark admitted it was him and went back to the car for my stuff he'd hidden!
He wasn't a keen angler but he was into scuba diving. I found that out when he came through my swim unnoticed till he popped up and scared the shit out of me! Lol.
