I actually think the humor aged surprisingly well, Austin may always be super horny and hitting on everything remotely female, but he also respects boundaries and understands consent.
I mean, it ages better than the obvious intentional paordy of James Bond that it is. at least in the sense that it's intentionally campy and made to emphasize it's ridiculousness rather than make it seem realistic.
I mean, art isnt created in a vacuum. I suppose I'm watching it through the lense of someone who isnt 13 too.
I dont think any of them became bad jokes but I definitely think some of the jokes are a bit more "potentially offensive" today than just lighthearted fun.
