Be A Clown - S1-E11
Continuity mistake: The Mayor is giving an inauguration speech. Look at the crowd in the long shot. It cuts closer, and you can see that the man in cowboy hat that was in the crowd moved behind the mayor on stage. A journalist in red tailleur also switches to lilac. (00:01:20)

Character mistake: The magician's name on the poster is "Proscuitto", which is a wrong spelling for Prosciutto (ham). The misspelling is inconsistent throughout the episode; it is wrong the first time Joker shows the poster, then it's fixed at the fun fair and on tv. The font used is also different.
