Go as the US budget crises! Something relevant and clever always is good in my book. You could go as Ke$ha or Lady GaGa, who have pretty good getups.
There are several options for funny costumes. A really funny one for couples is to go as a plug and a socket. The plug actually plugs right into the socket.
it depends. if you like dorthy then it would be a good costume. if you just wanna wear something cute then yes, it is a good costume.
