On the Hiwassee tailwater in TN once I gutted a trout and found a 2 nymph rig in his gut, tippet still in tact. Toccoa River once yielded a trout belly whose gut looked like a rainbow because it had multiple blobs of different colors of powerbait and not one shred of anything else. Those aren't all too weird I don't guess. I am interested in to see what others say assuming everyone isn't strictly C&R
