I've recycled and experimented with all kinds of left-over food as bait: bread, ham, bacon, shrimp, turkey.... "Whatever that guy over there just wasted, may I have it for bait?" Yes, I've actually asked servers to give me left overs so I can go fishing.
Sand fleas? They do NOT need to be fresh to be effective. We've microwaved them and frozen them. Yep, they still catch fish.
Doughballs catch just about any small-mouthed fish I've come across: bass, brim, suckers, shiners, trout, and yes... grunts, snappers, chubs etc. "What are you using?" "Left-over doughballs from my airport sandwich." "No kidding?" "No kidding." Doughballs are even better with a little mayonnaise :)
However, I've never experimented with hardware. Honestly, it never occurred to me. Until now.
This is inspired... and very funny~!
