Looking for interesting activities in DC. The weirder the better?

I am looking to make a checklist of things to do in the DC area while I am living here. I don't really want the ordinary stuff like museums or restaurants or whatever. I'd like to find some more interesting, obscure activities, sites, etc. So if you have any, feel free to share.Looking for interesting activities in DC. The weirder the better?
For starters, pick up a copy of the Mondo DC travel guide of wacky and bizarre sites in the area; some other off-the-beaten-track attractions/activities include:



* National Museum of Health and Medicine at Walter Reed Army Medical Center

* The Exorcist Steps in Georgetown

* National Cryptologic Museum

* The Roman catacombs under the Franciscan Monastery (Brookland)

* Dinosaur Land (Winchester, VA)

* The Great Stalacpipe Organ at Luray Caverns

* Local ghost tours
A few things I would check out are:



1. The Paddle Boats at the Tidal Basin, it's only 8 bucks for a 2 passenger boat and you get really cool views of the monuments.

2. Screen on the Green which project movies onto a huge screen on the National Mall and it's totally free. It happens during the summer on Monday nights.

3. The Commandants Own, since you are in DC I would really check this out. This is pretty much the only place you can see this happen. It goes on I think from May - August on Friday Evenings at the Marine Barracks and Tuesday evenings at the the U.S. Marine Corps War Memorial.

4. DC Kite Festival, it's pretty cool to see a bunch of kites flying above the Mall. Always happens in March.

5. Folk Life Festival, which happens in the summer on the National Mall. It's pretty cool if you're into crafts and things.



I know I mentioned stuff that happens in the summer, but DC is just so cold!Looking for interesting activities in DC. The weirder the better?
