A Lincoln Log Bongo Drum
is constructed entirely of an empty Lincoln Log container. A Lincoln Log container is made of a cardboard tube with a tin top and bottom.
If you sit on the floor and bang on the Lincoln Log Bongo Drum, you can eventually drive your mom to madness. I'm sure that this was the intent of the Hasbro corporation from the start. Because everyone knows that children of insane moms live with their grandparents, who will obviously buy their grandchildren more stuff from the Hasbro corporation!
