Bob’s your uncle! And Fanny’s your aunt!

The crocodile/alligator thing is still being used. At least it has been used the last few years with my kids. I'm sure other parents still use it with theirs even nowadays.

I'm a big user of "later, gator" with friends, but only when I am in a good mood.

Regardless of mood, I would probably use that phrase with an actual alligator if I were to encounter one, but oddly they are remarkably scarce where I am (though "take care, bear" comes in handy during the odd hike).

In fact, now that the seed has been planted, I have added "say 'later gator' to an actual alligator" to my long-term bucket list.

“See ya later alligator” was, like, seven decades ago.

Are you really telling me that you’ve all travelled Back to the Future?

Talking of Fanny. It is curious that, in slang, the word means, well, different sides of the same coin, so to speak, in British and American English.

In Australia as a child we used Bob's your uncle- doubly amusing as we had an uncle Bob. Fanny didn't mean what it does in UK (from bottom) US (derriere)
Hence Fanny by Gaslight fell rather flat.

Also
Cop ya later (cop= Aussie slang for catch/see you.

See ya round like rissolle

A: See ya
B: Not if I see you first

I used the alligator and crocodile too. Even taught it to a few kids.

We had an uncle Bob as well, so the expression confused me as a child. I'd never heard the "and Fanny's your aunt" response though. However, the concept of Aunt Fanny seems to be present in UK folk memory, e.g.

"Well, I'll chase my Aunt Fanny round the gasworks"

as an expression of surprise. (Used similarly to "Well, I'll go to the foot of our stairs", which to me, has a "northern" ring to it).
