I've had my fair share of followers....
Beaver as I was too close to his dam / hut
Geese / Ducks looking for a handout
Snake, which creeped me out so I slapped it on the noggin' w/ my rod tip
A boater trying to ID what I was using to catch fish...I finally caved in and asked if I could him. He was an older gent w/ his grandkid and they were strugglin' while I wasn't. I gave them a bag of what I was using and walked them through how to use. When they came back to the ramp an hour or so later, he tried to give me money and told me it changed their day / week as they were there the day prior and only got two bites.
And my favorite...a drift sock. I somehow snagged it with my lower unit while drifting into a cove. Luckily it got shallow and I raised my motor to see it dragging behind us 5-10' back
