Are Billy Connolly's jokes about Glasgow birthday caird pish?

So, I was having a few cans with my friend this morning and talking about the city and he hits out with this question. Let me state right away that I absolutely do not think that they're birthday caird pish - I fucking love them. Their point was that he leaned into stereotypes but used humour to paint the city in a better light than it deserved. The examples given were the classics like 'Two Scotsmen in Rome' and his general comments about the city, like the one about having a roll and square sausage and a cup of tea. I told him he was full of shite and that it just reflected real life in a funny, masterful way because, you know, he's a fucking Glaswegian comedian. But it got me thinking about how we represent ourselves anyway.

I'm interested in people's opinions, especially from people not originally from here. I'll say that everyone I've known from other places has loved him and found him bang on. Even the people I showed him to abroad laughed their arses off and in no way was it as if they were laughing AT Glasgow.

Thoughts?
