I got this one in an email today of all days and immediately thought that it would have to be an April Fool's joke. However, I was wrong, it is real. There are photos!
This was a pretty interesting story from The Sunday Wichita, Kansas Eagle Newspaper a couple of weeks ago. A resident in the area saw a ball bouncing around kind of strange in a nearby pond and went to investigate. It turned out to be a flathead catfish who had obviously tried to swallow a child's basketball which became stuck in its mouth!!
The fish was totally exhausted from trying to dive, but unable to because the ball would always bring him back up to the surface. The resident tried numerous times to get the ball out, but was unsuccessful. He finally had his wife cut the ball in order to deflate it and release the hungry catfish.
You probably wouldn't have believed this, if you hadn't seen the following pictures...
Just to prove to myself that this was legit, I did a little research of my own and found the Snopes story, which references the actual newspaper article.
