That reminds me of a time I was with a school group on a fishing excursion. I'd been working with several of the school's Outdoor Biology classes, showing them how to cast jig, paint them and either tie up with hair/feathers or plastics that I showed them how to make. On this excursion we were at a private lake with some dandy crappies and sunfish in it. The class instructor brought waxies thinking that the fish might hit better. I had a group of about six with me and showed a couple how to hook the waxie. When I got one waxie out of the container two were hanging onto each other, so I slipped one between my lips while I was working with the other one. There were 4 girls in this group and they all were, like ooooooo, yuck. I explained that the bugs were a sealed unit. All they did was grow, never excreting anything, that they were very clean in fact. The next thing I know I have three of these girls fishing with a waxie on their jigs and another in their lips in case there weren't any more handy if they lost the one on the line. The class instructor came along as this group seemed to be catching fish right and left. Of course he noticed the girls with the waxies in the chops and asked what was up. I just stood back and listened to the chatter and smiled. He came past me an shook his head saying "I don't know what you told them but I have never had a group where the girls were undaunted by bugs, let alkone carrying spares in their mouths?. He walked away laughing.

That's just cool.

 Yes. I even use a shorter insert to make a hard nose tube.

Curious about the do-it tube bait molds.  It seems to me that if I were to shoot one without using the insert I would have a solid body tube for TR fishing or maybe a Ned rig.  Am I correct in this assumption?
