I don't have a horse in this race (I'm Canadian), but this reads to me like a bad joke, not a serious attempt at breast-enlargement hypnotism.
It was always terrible to make sexist jokes like this, but we've come a long way since #MeToo in 2017 to start challenging some of the systems of the patriarchy. In 2013, I'm pretty sure people would have agreed the joke was in bad taste, but I don't think anyone would have been cancelled for it.
If we start retroactively cancelling people for things they said decades ago, then that'll basically include all comedians and likely most people with lots of video footage of them in general. (Have you tried watching any fiction shows from the 90s or even early 00s lately? They all have intolerable sexism, to me anyway.) Isn't it a good thing that people are changing with the times, and becoming more aware?
(Note: I have no idea who this is, so maybe I'm missing some important context.)
