Which is used more often, Martian arts or Maritime arts?

Maritime of course. Define martian arts.

Maybe he meant martial arts.

I watered an auction of Martian arts once. Bidding of a particular statue was astronomical.
A landscape painting was out of this world.
I bid on a painting titled Craters And Crevasses, but it went far above my budget.

@filmfann, I believe he is being punny.

Edit: I typed attended. I don’t know why it changed to watered.
