O_O Wow, I think my choice would be #2. . . If I got 2 million dollars, of course I would get a tattoo on my forehead.. . . I think I would have it say something like "crap" , or "insert here", or maybe just a big dollar-sized keyhole.
What I would do anyway would be to use the money to have the tattoo removed anyway >_< , then buy a house, etc.
