I stumbled across this video of a guy "accidentally" throwing his fishing rod into the lake. I put quotation marks around "accidentally" because it looks like he did it on purpose for a video. His hand opened up on the cast. Here it is, you be the judge.

Another video I found appears to not only be a legit losing of a rod, but also more subtle. The guy is fishing out of a canoe and gets a quick bite. He reels it in, takes it off the hook and releases it. But watch his rod the whole time.

Kids are cute. This little guy had his pole taken out of his hands by the fish he was trying to reel in. His reaction was priceless!
