Honestly, that's pretty incorrect.

Nursery rhymes/fables?

Airplane whistles?

Homage to his older funny brother?

Being rich?

Animals are gay?

Weird/wonderful facts about animals?

Oxford Union pamphlet?

Pissing in the sink when he was broke?

Even "Fame", which was about...fame.

That's just stuff I remember off the top of my head because they were all class and really funny. Not to mention that his religion/God ones are amongst some of the best stand up material I've seen, who else has gone on stage and disected the nonsense written in the Bible or made fun of a hilariously badly illustrated childrens religious book. Actually think Ricky is at his best when mixing things up with more presentational stand up using things on a big screen or bringing in than pure talking for an hour as his last few specials have been.

I will agree though, his last few standups have been pretty repetitive/sub par with far too much focus on trans and social media arguments with numpties. Yes, we get it, there's alot of idiots spouting nonsense on the internet and attempting to impose their views on the rest of society. It was funny the first time you read out some Tweets and mocked the stupidity, not so much the next few times.

But ultimately this is pretty normal for stand up comics, especially the biggest/best ones. They have specials where they peak as a comic and raise the bar giving their best ideas/views/topics etc, then they run out of material and become repetitive, especially since their delivery is the same and so they become quite predictable. Noone is immune, not even GOAT comics like Pryor who had some pretty awful stand up shows towards the end.
