I think they're too long for what they say, which isn't an awful lot. The second one is quite funny, but you'd have to develop it into a humorous site about the kind of people you wish would leave you alone, and I don't think the joke would last as long as the first few sentences. Or maybe a funny site about how people got sacked and what was said to them.
I suppose bigoceanwaves.com might be suited to a surfing site, but I'm not sure surfers would put that into the search engine. Maybe if someone had lots of pics of high seas they could use it as a showcase, but that's pretty limited in a world where there's flickr.
