This one takes the cake. A bunch of us were plunking a fast dropping high water. After a few hours of no action my friend went back to his rig to get his drift rod, while leaving his plunking set up fishing. As soon as he was out of sight I took a spool of line tied to a snap swivel, clipped it to his mainline and slid it out into the river, ran the line down past a couple of rod holders and back up to my folding chair. When he returned and was trying to rig up for drifting I'd give the line a little jerk to make his bell ring. He'd stop and walk over to his rod and wait. He'd return to riggin up and another little tug and ring. He was getting impatient with this pesky "fish". I let a couple of minutes go by and let him have it. I had that bell ringing to the tune of a twenty-plus pounder. He dropped everything and ran down to his rod to set the hook. He pulled back and I pulled forth until the snap swivel came up out of the water and the cat was out of the bag. Everyone there was in on it and it was the most hilarious thing I've ever seen!
