Sand Haus

Something enthusiastically mentioned by Derrick Whipple (played by Eric Wareheim) during the Jim & Derrick promo for the Adult Swim Beach Party in Panama City Beach. It is never explained what a Sand Haus is exactly, but its primary use is apparently to get real wet up in it. Anything else, one must assume, is secondary.

Yo we're gonna get real wet up in that Sand Haus
