Because you can?

Why else would you exhibit the same work in two different places?
The Museum of Modern Art has this stack, by Felix Gonzalez-Torres, in two galleries–the Prints Galleries and the Contemporary Gallery. I’m trying to think of any other artist whose work could be shown in two places at once.
Meanwhile, the new building is literally awe-inspiring. My biggest fear was that the gargantuan galleries would dwarf the art. It’s not even close.
I remember during the OK trial, when Margaret Cho ran into Johnny Cochrane at the Mondrian, she gushed, “I love your show!” The only reason I didn’t use that line with Mike Ovitz was because his case wasn’t on TV. Still, we had a good time trading war stories from our days workin’ for the Mouse.
Oh, wait, I think I dropped something.
