LOL. They were pretty tame. A few off the top of my head that I desperately hung on to:
flomp.com
sdnow.com
onetogo.com
buymycars.com
tripbot.com - I paid $5k for that one. Let it expire.
I'll have to dig around to find a better list.
I had bikinicontest.com a long ways back... verrrrrry interesting backstory on that one.
I bought shopbot.com one Thankgsiving morning in the 90's for $35. Excite had mistakenly let it expire. That domain name has made me tens of thousands. A guy offered me $1 million for it the next day. I stupidly declined. I had it sold at one point for $4.5 million, but the buyer couldn't raise funds so the sale never happened.
I also have animotion.com. The band emails me every once in a while
It was also in a Simpsons episode.
