JB needs to go as Chung Ling Soo and needs to be very politically incorrect (as it would be historically accurate). He also needs to produce a bowl of water from a cloth and then produce a small child (that's historically accurate too).
Andrei must costume himself as Orson Welles (which means he better start eating himself to death pretty soon). Here's some reference:
J. Bayme See if you can try to get like a little pack to go on your stomach and try to look like Chris Kenner and with glasses you can see fine enough. Or you can dress like the Flinstones You be Fred and Andrei can be barney. Or Maybe Something like Whitney Houston And Bobby Brown. Or maybe something like Cheerleaders and Cheer to Katie and Chris. IM just givin some random ideas but these are some of what my friends did to do for a prank. You know how about a spoof of somebody like david blaine or david copperfield im not sure if you would like to or not. Maybe somethin like weirdalyankavik. What about andrei lucy and j ricky
Andrei: Im thinking more of a Drunken German dude in, germans traditional clothing eg. Example Here.
JB : The fun thing would be if you were dressed like the girl there but that would mean you would be similar.
You could be an ipod That would be awesome, or a condom. This would be the best for you! (JK)
I think a colorful 60´s Hippie would look great on you .
