Yup, late night drunk good-idea domains are my specialty. Here's my 2 favs.
1. MyHappy18.com - I wanted to set up an online weekely mag that girls who just hit 18 could send in their pics and all that shit. Like I said, drunk idea, sounded much much better when I was plastered.
2. Iwanttodoporn.com - My first drunken thought was an adult myspace for industry peeps and the people who want to be them........my first sober thought was "great I waisted more stupid money."
I have others, but none of them spring to mind like those two do........
