I found the remains of this sticker on a park bench today:
The face is Serhiy Kivalov's - aka Kidalov, pidrahui! - and the text says he has to be in jail. Signed by Pora (not sure which one, the party or the movement.)
He's in parliament now, however, or will soon be there, as he is #27 on the Party of the Regions' list.
Obviously, this is one of the reasons I didn't vote for Yushchenko's Our Ukraine Bloc in this election.
