contrabass saxaphone?

holy shit, they're huge! the contrabass is twice the size of a bari... watch:
also worth checking out this short video of a goofy guy playing one. james carter plays a mean bass sax (slightly smaller) here. there is a sax even lower, the subcontrabass sax... really though, if i was going to get a huge wind instrument it would have to be the contrabassoon, or be like this lady and have both.
