The Thai ambassador to Australia has sent a strongly-worded letter to Channel Ten after the network aired a skit making light of the recent death of the nation's king.

In the letter dated October 18, Ambassador Chirachai Punkrasin said a segment on Monday's episode of Have You Been Paying Attention? was "very inappropriate, disrespectful, and certainly not amusing".

"While it may not be the intention of the Network 10 to cause offence, the programme needs to show greater cultural sensitivity and media professionalism when it deals with a topic that makes reference to another country, institution or culture," Mr Punkrasin wrote.

Have You Been Paying Attention? is a weekly comedy-quiz program on Ten which challenges a panel of comedians and entertainers to remember the events of the week and this week showed a video clip of a Thai woman wailing over the death of Thailand's beloved monarch, King Bhumibol Adulyadej.
