I bought a powerball ticket yesterday. This stuff is top of mind for me right now.

Ooh, that would've been a good one.

The pools have to have waterslides too, not the crappy blue one slope slides either, I mean real genuine waterslides. A lazy river would be nice too.

It has to look like no one would be comfortable walking around in their underwear because it doesn't look or feel like a home. Because walking through a museum in your underwear is frowned upon.

Daaaaaaaaang. My bad, m'lord.

And +1 for orgy room. OR SHOULD I SAY +5 AMIRITE?

To be a mansion this day you need the hybrid orgy/spelunking room.

If it has scantily clad hot broads that cater to a mans every need, then it is a mansion in my book

We have friends that have this little sort of courtyard where they have a small basketball court. It's not their yard, they have a separate yard. The courtyard sits off the kitchen and then there's other walls of the house around it so that it looks sort of like a little town square.

When I hear the word mansion I always think of Jed Clampett's place in Beverly Hills. That's the benchmark for me.

Where's the square footage option? Fail thread.

When I think mansion ... it has to be upscale and "larger than your typical big home" and "expensive", often with more bedrooms than a 5 person family requires ... and it would have a number of the items you listed in the poll.
