To be honest, if you were going to get anything for these I would stick some content up quickly and see what the stats are like. Because if this is a flash in the pan, they could be worthless in a few weeks.
I thought about bidding for parishiltonforum.com at Snapnames ... wonder if anyone did get that.
I agree with the above posts. Things like this don't last very long. Although while it's in the spotlight you might get some traffic with a little bit of content. See if you can make some profit before public interest goes elsewhere.
"News/Recent events" domains fizzle after awhile. I'm sure parishiltonsextape.com isn't of much/any value anymore. If you can get $10 from each of them, don't let the offer pass you by.
