I was going to start a thread on this myself - I think it's hilarious (and I've just realised I completely forgot to tape it last night, assuming it was on with the bank holiday). The casting is spot-on, and having worked for a Jewish-run company, the characters are very recognisable to me.
My mother, bless her, asked after last week's episode 'So is Simon Amstell really gay or is it just for the program?'
