It's common to say that sulfur/natural gas smells "like rotten eggs" but I've probably not smelled a rotten egg in isolation for 40 years. But since I'm familiar with sulfur-type smells I could probably figure it out. I expect a future of bad and rotten eggs in our supermarkets...

I'm familiar with the smells of sulfur (at least memories from decades ago), natural gas additives (mercaptan) and having chickens that like to lay in random hidden places, rotten eggs.

I don't think that there's much overlap in the scent profiles. Maybe a diluted rotten egg is similar to that smell of making black powder as a child, but not much.

Storytime, please?

Not much to say. Couldn't buy gunpowder as a 12-year-old, but the drug store would sell you saltpeter (KNO4?) if you said your mom was using it to cure ham and sulfur (I think it was used on wounds) and it was easy to make charcoal and grind it to a powder.

Mix the three together and stuff it into a small closed-end tube made from newspaper and scotch tape, with a piece of powder-infused cotton string for a fuze and you had yourself a rocket.
