Mr. Bean's car has been broken into, and he is trying to explain to the police woman what was taken. Of course, there's "sponsored silence", which means he can't speak and has to mime it to her.
I kept wondering: why can't Bean write it down for her?
Either way, other than waving the "Sponsored Tea Drinking", "Sponsored Godpiece Wearing" etc. signs around, that is about as amusing as this episode gets.
The mime part is okay, but not the best Bean and Rowan Atkinson have to offer. Perhaps it was the script that didn't work this time around, or the attempted concept.
