There were no more complaints than you'd normally get for an average show with swear words in. The Daily Mail exaggerated it massively and as a piece de resistance, printed the jokes it considered massively offensive in a newspaper you could buy and read way before the 9pm watershed this show was broadcast after.
It's as if they live up to their reputation on purpose.
There were several jokes that could have recieved complaints but only the royal ones get highlighted! That said, its a show full of comedians, made for comedy fans. If you don't like comedy and are going to take offence to jokes, dont watch! Simples!
I hate it when the press pamper around stupid little things like this
