At least this question is broadcast after the watershed. But ITV have a repeat of this episode later on in the week outside of the watershed which is on during the afternoon. I know the question is about art but still nice one ITV.
It’s not really an issue as the term wasn’t in English (although easily translatable) and it’s pretty low level swearing if it was.
I thought the single player format worked well for celebrity and you felt more invested in their performance than if they were in pairs. I guess having pair meant it was more likely people would have a celeb they liked on the show though, so that’s one reason I can think it’s nearly always been done that way in the past.
