Any soap, talent show, dance show or Big Brother.
Oh, and right now? Limmy's Show.
Now, I have a wide-ranging sense of humour from the darkest, blackest & most out-there to the fluffy, classic British sitcom - but I fail to see what's funny or where the laughs are supposed to go in this. Other comedians sing its praises on Twitter, but I'm beginning to suspect that as they're BBC stars they're contractually obliged to plug other BBC comedies which are low in the ratings to try and get their numbers up!
