More Karneval ideas! But it's a bit of a tradition to dress up to mock news figures, and it's been a generous year so far.
Hosni Mubarak: VERY shiny black wig, suit, and sign (preferably sandwich board) that reads, "Will Dictate For Food"
Muammar Gaddafi (your spelling may vary): Wrap yourself in drapes, get a pathetic set of chin-pubes and babble about how al-Qaeda and the West are conspiring to oust you.
Karl-Theodor zu Guttenberg: Get a box for a photocopier (you DO have one, right?) and label it "Guttenberg Research Labs"
Silvio Berlusconi: A Grim Reaper mask, slicked-back hair, an Italian suit (or AC Milan jersey in a pinch) and dolls (perferably toddlers or young girls) on each hand.
John Galliano: Get a Dior t-shirt, then slap a swastika on it. Not recommended for readers residing in Germany*.
* Which, of course, kind of defeats the purpose of a Karneval costume, I guess.
