It started as a bit of a joke on the "That's a good band name" line. It became "That's a good domain name". Yes, I went to a stem college.
Anyway, i've started 4 pretty decent businesses based entirely off that bit. My friends and I would be riffing out behind the pizza place/bar we frequented, someone would say something and then "That's a good domain name" comes out. I'd make a quick note and think about it for a few days. I found that if I come back to it after a week or so then it's maybe worth something.
Business and domain names can make or break a company.
On top of all that, i've also bought and then sold hundreds of domains for a profit based off this bit. I use various registars when they have sales, buy em up cheap for a few years, then park em.
After reading the OP, it's kinda funny. I did something similar with a garlic grower back in the early 00's. I had a domain, my brother worked for a garlic farmer, the farmer wanted to export to asia. It worked out well for a few years.
