I'm pretty sure I'd be terrible at it. I can be very funny in real life, but not in a way that translates to stand-up. Stand-up takes more time and effort than it appears.
Your sausage Starmer joke didn't make me laugh, sorry, but it's more in the telling than what's written down.
If you tried it and nobody laughed then you could maybe add "well, dunno why you aren't laughing. Told it to me Mum and she said my sausage joke was a banger.
Told it to my best mate and he said yep, she is! I shook my head, just like I am now, and said "your Mum" jokes are old-fashioned now. Not like my best mate's Mum, she's not old fashioned, she's a delightful person, finger right on the zeitgeist like Schofield's finger's always on the intern's call button, always tries not to offend anyone. Anyway, so, my best mate, Hitler Jr, said..."
Pause for laughter or silence.. "I'm known for that sausage joke in Germany, though. At least, they said I was known for the worst joke..."
Or with a cleverer audience, go for "they said it was 'total Scheisse.' which I wasn't expecting. My agent told me that's Berliner German for 'really funny.'" You know, like we say the bollocks? Makes sense, right? Think she might have been lying though, because I looked her name up, and..." Etc.
Or build up on it in a way that's actually funny and that you can remember. Something personal to you or to the personality you've made up.
I have one good acquaintance who's a relatively successful comedian (it's her main job, anyway), and one close friend who did well for a while then decided it wasn't for her. They did both have some training. My friend who has stopped doing stand-up still benefited from it - a course at the comedy store, I think. It made her more confident and better and public speaking - she was always good at that but she got even better - and she made a lot of friends. I'm very glad to say that, having seen them both live, they were both genuinely really funny. I've had a couple of other acquaintances try it out (one with some success) and they weren't funny. Still respect them for going for it though.
Maybe look into courses near you, or short intensive week-long ones somewhere you'd want to visit.
Open mics will also let you try out any comedy TBH. The problem with really open open mics is that the only audience is likely to be your mates and other comedians, so it can be hard to tell whether you're funny or they're kind. I think sometimes they also don't laugh when it actually is funny - based on people I've seen - because it's not the right set-up. But it's still a way to try it out and it's brave to do it.
