You know, you joke, but it's not as crazy as it sounds. I'm a post op trans woman, and I've had a pap smear before. The US's NIH website actually used to specifically recommend that for post op trans women every five years or so. The recommendation has since been purged along with all other trans health info, but it used to actually be an official recommendation. Here's a blog post going into more detail on it:

Obviously trans women can't specifically get cervical cancer. But the same test, a pap smear, tests for other vaginal cancers that post-op trans women and nonbinary folks can get. Anyone with a vagina needs a pap smear, regardless of gender assigned at birth or transitioned gender.
