Hey, basket weaving and leather work were super fun, and I have all cool ones like shotgun, archery and rifle. The most boring are probably your citizenship badges. Don't knock it till you try it.
Safety was the most boring badge, and quite a bear too. Lots of memorization. It was required afaik too, at least back in the 90s. Had a reputation as blocking advancement to a higher rank, I think Life.
Oh I have the leather working merit badge, I loved it! The particulars of how to work with hide and stamp it was a neat arts-and-crafts activity that I hadn't realized.
Basket weaving was considered the slacker badge (for my troop at least) to work on during summer camp because it had 2 requirements and it generally took a day to complete. I was more interested in rock climbing / canoeing / forestry etc - we're in the wood for a week, why waste it?
